The separation of Church and State is a given, though of course some people will still attempt to shoehorn their religious beliefs into law under any pretext they think is feasible much like what is happening with our friends to the south and in many other places with religiously fascist governments (Iran, Afghanistan, Sudan, etc.); however, that doesn't mean people should be criminalized for their beliefs. Think of what you're proposing; someone attends church on Sunday, after it has been criminalized. They are arrested and thrown into prison... why? What harm did they bring to their community? It is somewhat of a fascist thing to do, no?

I have met many religious people in my life, and the majority of them are amazing people that truly believe in serving humanity in the name of their god. I personally think it's silly that they need that justification to do what they do, but it's an effective emotional driver. That being said, there are certainly people that have very extreme views based entirely on their religious beliefs. Christo-fascist movements in the US, like the well-funded group of "Christians" that successfully lobbied the government to repeal laws that protected the right to abortions, are prime examples.

I do agree that religion has had a negative effect on society as a whole, especially when considering recent and not so recent atrocities committed in the name of their God; like the millions of missing and murdered Indigenous children that were attending residential schools, the women currently being treated like property in Afghanistan, and more women in America that have lost access to safe abortions. Not to mention the crusades...

All in all, it's pretty horrendous what religion has done, but outright banning it won't solve the problem. Any form of prohibition doesn't really work that well, and only forces people to go outside of the law potentially putting them in precarious situations. Heck, the people that use religion as justification for being horrible human beings might simply find a different justification and then only innocent people will become criminals for their beliefs.
