Imagine being such a snowflake that someone burning your holy book of choice causes you to react with rage and violence. Absolutely feral, animalistic mentality. If your faith is genuinely strong you should not care at all, as their action only harms their relationship with the God you know to be true, and you know with 100% certainty that God will eventually have the final word. And no I'm not an atheist by any means.
It's like you've channelled the Ghost of Hitler. LOL. I suppose he got the idea from the Marxists that burned Jewish texts in 1901 and between 1914-1917, which was followed by the progroms.
Imagine being such a snowflake that you got upset when another individual was enraged by someone of another faith, sect, or no faith, discriminated against his religion by destroying your sacred text via arson in order to make a political point.
However, I do agree with people being allowed to burn a Quran. That's freedom of speech. You can also burn the US or Mexican Flag. However, I suppose you can criminalize an arsonist for setting a fire in a public place, and make intent to keep warm or cook an affirmative defense.
