But some people don't do the "harmlessly" part, EG, Westboro Baptists, Islamic extremists, the idiot republican fundamentalists ruining America, the Vatican sheltering pedophiles and doing nothing to stop children getting raped/molested.

You are judging the many by the actions of the few.
I could just as easily say letting people place their faith in democracy is evil and it leads to horrible things.
Look at the election that led to Hitler, or those that led to crazy dictatorships in the Middle East.
To which the opposing side would say "Yes, but those are rigged or people were ignorant of what was actually happening" Which is the same thing with those minorities. They are perverting religion for their own goals.

harmlessly is no big deal, when you try to promote it as fact then we have problems

Harmless. Yeah.

You know there are religious wars right?

If you can find me ONE
ANY purely RELIGIOUS war, I will applaud you.
Most "religious wars" are actually for land, political power, resources, etc.

The Huguenot Wars.

You mean the civil wars fought by the nobles in order to gain more land and money?
That "purely religious war"

Albigensian Crusade
Boxer Rebellion
St. Bartholemew Massacre
Shimabara Revolt
Sikh uprising
Spanish Inquisition
Thirty Years War

Now before you say anything I'm not doing this to defend atheism nor am I defending religion. I'm doing this purely for the fun of it.

Any Crusade or war started by the Catholic church, may look like it has religious intention, but the Catholic Church is as much a political power as it is a Religious one, and war fought by them is not just for their religion to be strongest, but for their grasp on the world, and so they would get paid, making it about 50/50 as to why they fight, the soldiers may fight because they believe in their God is best, but the Church sends them out for political power.
Like the Thirty Years War was political. The Catholic church was worried about those lands becoming protestant and not paying taxes to the Church, and therefore not actually religious, it was done for monetary and political power. You can tell it's not purely religious since France (a catholic state) was siding with Protestants.
The Boxer Rebellion was equally against the influx of Christianity, and was opposing the idea of foreign imperialism like they had seen before, it was fought for a nation, not a religion.
The Sikh Uprising information I have found is hardly a war, it seems like more of a hostage situation and a few attacks meant to seek the creation of a free Sikh-based state much like Pakistan is to Muslims. Again, religious, but also Political.
Again, the St Bart. Massacre was a single incident, the French Wars of Religion was again, about religion, but also for political control of the aristocratic houses that lead the forces.
The Shimabara Rebellion was mainly due to harsh taxes, not really religious because the Dutch were also Christian, it was more of class war than a religious one.
Spanish Inquisition, like the Thirty Years war, largely religious, but again, was still for political control, they wanted to oppress the other forces so the Church could maintain power.

While all good examples and have to do with Religion, none of these were truly Religious wars fought SOLELY for religion, most of them are wars that were fought under the guise of religion or divided by religion.

Cool, you really seem to know what you're talking about, I'm impressed.

Because people, like this dumbfuck above, believe their belief is so superior.

Let everyone practice whatever faith they want.

I'm pretty sure he has no beliefs in any religion.
