I am for pulling ALL tax exemptions including Clinton foundations. Churches used to be the safety net and therefore got tax exemptions.

The Constitution says nothing about "separation of church and state" It does say Congress shall make no law respecting an establishment of religion or prohibiting the free exercise thereof". It seems to me that you completely misread that first part and completely ignore the second.
How did the Founding Fathers understand the term "an establishment of religion?" To them it meant something like the Church of England where the King is the head of the church, attendance is mandated by law and the church is supported by government. That is like ancient history to us but it was fairly recent history to them.
As for Thomas Jefferson I don't know what you meant be that term FF but I do know that following the American Revolution he was heavily influenced by the atheism of the French Revolution and became a Unitarian although I don't think he actually became an atheist. In his later years when he was near death he returned to God and reconciled with his old rival John Adams.
Lastly the only religion in this country that considers itself exempt from the law is the woketard religion of the Left. Yes they are a religion, they have all the worst aspects of a pagan religious cult.

@magapundit FF = Founding Father. Jefferson was a Founding Father, and he did not think Christianity was required for the function of American society. Thomas Paine and Ethan Allen were Deists, not Christians. Benjamin Franklin and James Monroe were skeptics and didn't believe in the supernaturalism of the Bible. So right off the bat, the video is wrong in saying the Founding Fathers wanted America to be specifically a Christian moral society. This is extremely evident in the First Amendment, as allowing religious freedom is antithetical to the First Commandment and Biblical dogma.

Establishment of Religion has a pretty clear definition. It means you can't create law exclusively based on a particular religious viewpoint. So something like saying same-sex couples cannot get married because the Bible says it is wrong is against the Constitution. If you say there is no separation of Church and State, then churches can be forced to pay property taxes, and people cannot be allowed to circumvent federal laws based on cherry-picked religious claims.

"free exercise thereof" - ok, so then if someone's religious belief is that prostitution or drug use is okay, then the government cannot interfere. So you agree with that, and are perfectly fine with both being legalized? Satanists believe in bodily autonomy, so they should be allowed to go around any abortion restrictions? People who have religious viewpoints that their gender identity is separate from what they were assigned at birth should be accommodated in all aspects? So you agree with all of that?

You sound sooooo smart using terms like "woketard religion of the Left". Sorry, but a political or social ideology is not the same as a religion. And you want to talk about cults... have you ever even seen Christianity? You also realize Christianity borrows about 90% from these "pagan cults"?

I think taxing religions is a great idea but I think it will take another linguistic sleight of hand like the "separation of church and state" to pull it off. However, discontinuing religious exemption from laws is tantamount to "prohibiting the free exercise thereof." There are some laws that are repugnant to devout Christians and refusal to participation in some activities is in itself an active part of exercising their faith.
