Let's make everything illegal legal and no one suffers consequences. Since pot is a good money maker let's tax murder and everything else. We are already on a moral decline. Let's go all the way there.
I'll bite on this message.
In that case, lets make things legal that ought to be illegal that are immoral. You say we are on a moral decline, so lets turn this back by making criminal to do any of the following: premarital sex, drunkenness anywhere (even at home), any other type of medicinal drug that may be beneficial to one's illness and/or quality of life, and not believing/following Jesus Christ.
Who cares about freedom of religion, we know we follow the one-true God, the Savior of the world Jesus Christ. It should be illegal to do anything contrary to God's word.
Why should we allow people the ability to abuse alcohol? Lock them up! Those immoral substance abusers! They add to the moral decay of society.
Lets give anyone who has ever engaged in premarital sex a criminal rap sheet. Carnal sins are specifically called out in the bible. This will be huge in stopping the moral decline of society.
Liberty sometimes means allowing people to do things that we don't necessarily agree with, provided they aren't taking anyone's free will away in the process. Liberty doesn't mean we only allow people to do things we personally think are moral. This is why the US has been the greatest country in recorded history. If you believe in less freedom, then ban all drugs/alcohol, not just marijuana, punish people who commit premarital sex...
