Not sure just how "supposed" his hatred of the Jews were. Hitler even referenced him as partial justification for their treatment the final solution. You can't get much worse than this:
At the beginning of his career, Martin Luther was apparently sympathetic to Jewish resistance to the Catholic Church. However, he expected the Jews to convert to his purified Christianity; when they did not, he turned violently against them.
Luther used violent and vulgar language throughout his career. While we do not expect religious figures to use this sort of language in the modern world, but it was not uncommon in the early 16th century.
The following are excerpts from Luther's work entitled "The Jews & their Lies":
I had made up my mind to write no more either about the
Jews or against them. But since I learned that these miserable and accursed people do not cease to lure to themselves even us, that is, the Christians, I have published this little book, so that I might be found among those who opposed such poisonous activities of the
Jews who warned the Christians to be on their guard against them. I would not have believed that a Christian could be duped by the
Jews into taking their exile and wretchedness upon himself. However, the devil is the god of the world, and wherever God's word is absent he has an easy task, not only with the weak but also with the strong. May God help us. Amen.

He did not call them Abraham's children, but a "brood of vipers" [Matt. 3:7]. Oh, that was too insulting for the noble blood and race of Israel, and they declared, "He has a demon' [Matt 11:18]. Our Lord also calls them a "brood of vipers"; furthermore in John 8 [:39,44] he states: "If you were Abraham's children ye would do what Abraham did.... You are of your father the devil. It was intolerable to them to hear that they were not Abraham's but the devil's children, nor can they bear to hear this today.

Therefore the blind
Jews are truly stupid fools...
* * *
Now just behold these miserable, blind, and senseless people ... their blindness and arrogance are as solid as an iron mountain.
* * *
Learn from this, dear Christian, what you are doing if you permit the blind
Jews to mislead you. Then the saying will truly apply, "When a blind man leads a blind man, both will fall into the pit" [cf. Luke 6:39]. You cannot learn anything from them except how to misunderstand the divine commandments...

Therefore be on your guard against the
Jews, knowing that wherever they have their synagogues, nothing is found but a den of devils in which sheer selfglory, conceit, lies, blasphemy, and defaming of God and men are practiced most maliciously and veheming his eyes on them.
* * *
Moreover, they are nothing but thieves and robbers who daily eat no morsel and wear no thread of clothing which they have not stolen and pilfered from us by means of their accursed usury. Thus they live from day to day, together with wife and child, by theft and robbery, as archthieves and robbers, in the most impenitent security.
* * *
However, they have not acquired a perfect mastery of the art of lying; they lie so clumsily and ineptly that anyone who is just a little observant can easily detect it. But for us Christians they stand as a terrifying example of God's wrath.
* * *
If I had to refute all the other articles of the Jewish faith, I should be obliged to write against them as much and for as long a time as they have used for inventing their lies that is, longer than two thousand years.
* * *
...Christ and his word can hardly be recognized because of the great vermin of human ordinances. However, let this suffice for the time being on their lies against doctrine or faith.
* * *
Did I not tell you earlier that a Jew is such a noble, precious jewel that God and all the angels dance when he farts?
* * *
Alas, it cannot be anything but the terrible wrath of God which permits anyone to sink into such abysmal, devilish, hellish, insane baseness, envy, and arrogance. If I were to avenge myself on the devil himself I should be unable to wish him such evil and misfortune as God's wrath inflicts on the
Jews, compelling them to lie and to blaspheme so monstrously, in violation of their own conscience. Anyway, they have their reward for constantly giving God the lie.
* * *
No, one should toss out these lazy rogues by the seat of their pants.
* * *
...but then eject them forever from this country. For, as we have heard, God's anger with them is so intense that gentle mercy will only tend to make them worse and worse, while sharp mercy will reform them but little. Therefore, in any case, away with them!
* * *
Over and above that we let them get rich on our sweat and blood, while we remain poor and they such the marrow from our bones.
* * *
I brief, dear princes and lords, those of you who have
Jews under your rule if my counsel does not please your, find better advice, so that you and we all can be rid of the unbearable, devilish burden of the
Jews, lest we become guilty sharers before God in the lies, blasphemy, the defamation, and the curses which the mad
Jews indulge in so freely and wantonly against the person of our Lord Jesus Christ, this dear mother, all Christians, all authority, and ourselves. Do not grant them protection, safeconduct, or communion with us.... .With this faithful counsel and warning I wish to cleanse and exonerate my conscience.
* * *
Let the government deal with them in this respect, as I have suggested. But whether the government acts or not, let everyone at least be guided by his own conscience and form for himself a definition or image of a Jew.
* * *
However, we must avoid confirming them in their wanton lying, slandering, cursing, and defaming. Nor dare we make ourselves partners in their devilish ranting and raving by shielding and protecting them, by giving them food, drink, and shelter, or by other neighborly
* * *
Therefore we Christians, in turn, are obliged not to tolerate their wanton and conscious blasphemy.
* * *
Accordingly, it must and dare not be considered a trifling matter but a most serious one to seek counsel against this and to save our souls from the
Jews, that is, from the devil and from eternal death.
