Listen to what you are saying.

I for one refuse to cower to those threatening violence in return for burning a piece of paper. Any person that threatens violence in retaliation to a symbolic action is not to be treated with tolerance or respect, because they themselves are not giving any.

How tolerant are those same people towards atheists or other religions?

The core of all of this is simply that, you taking offense, whatever that means, should not be enforced by the state in the form of punishing me. It is a slippery slope that can't end well.

Take whatever offense you want, ban it in your private house or business, just keep the government out of deciding what is "offensive" and what is a matter of protest.

I for one find a lot of the text inside the Bible / Qur'an idiotic / offensive, but I'd never advocate for the government to step in and ban the books.
