I can understand that if alot of bad things happened to her because of religion she can have alot of hate for it (if that's true at all), but still acting like a complete douche because of it is not really the best way for people to understand your point.

Religion is a tool that politicians can use to manipulate the masses, remove religion and they'll use something else whether it's "Master race" Or something of that nature, the problem is not religion, it's A**holes in power who turn people against each other for their own gain.
