As have already opined, you have absolutely BUTCHERED (pardon the pun) the obvious meaning of those Romans 14 passages.
For pity's sake man they are talking about gentiles eating unclean foods and meat sacrificed to idols. And how to deal with it within the Church. Nothing more than that.
Rom 14:2
For one believeth that he may eat all things: another, who is weak, eateth herbs.
Rom 14:3
Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him.
Rom 14:14
I know, and am persuaded by the Lord Jesus, that
there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him
it is unclean.
Rom 14:21
It is good neither to eat flesh, nor to drink wine, nor
any thing whereby thy brother stumbleth, or is offended, or is made weak.
