Not something anyone should be killed or threatened for, but it's still being an asshole on purpose.

What’s not okay: To expect others to submit to rules of your worldview. Especially if others do not share this view or agree to the rule.

You have the right to believe whatever you like, but don’t expect me to follow. Because I have the same right.

This applies to acts which do not harm anybody or anything, like destroying a copy of a book which you own, without eradicating the book from existence or taking it from others.

Otherwise, we play the victim game. I can do that too! Look, I’m an atheist. This is a very serious thing for me. I feel appalled by the idea that more than 200 years after the enlightenment (just to name one of many reasons), people still believe and share religious ideas. The abrahamic scriptures are riddled with hate speech and endorsements of violence. To call these text collections ‘holy’ is an insult to everything I hold dear, like science and human rights. I’m offended by their mere existence, and perceive public displays as a personal offense to my worldview. I demand everybody in every country to respect my feelings and stop these atrocious acts.

Of course the sane alternative would be to thicken my skin, learn to deal with my emotions (which means I deal with them, not externalizing), respect differences as long as they do no harm.

These book burnings only exist because people make an unjustified fuzz about it, occasionally in a violent way. You can have your religion with all it’s rules, but you cannot expect people to apply who don’t subscribe.

I would not want to be working in the Danish embassy in Iraq right now..

That's like, the stupidest witch hunt.

They could be protesting for actual issues like climate change, but they are over there burning books. And nobody knows what they are trying to do.
