I can't talk for all the Muslims as you know, neither do the pastor or you guys represent all the people who live in the UK or have the same religion as you.
Islam is about peace, (you have probably heard that about 10000 times by now). It is a very strict religion too. Just because someone is a Muslim, doesn't mean they will go to heaven. It's up to God. Even saying or thinking, damn I've done bad things I might go hell, is not right.
I haven't seen any of these protests regarding burning the bible or other books, however I have seen the US flags, and effergys of George bush. This was after 9/11 and the war in Afghanistan/Iraq. You could understand that people are angry, but yes it isn't the right way to go about things.
But my question is this, where are flags/effergys, and then where are holy books? The importance and level of difference is drastic.
It surprises me some people think burning the Qur'an wouldn't cause uproar. I hope they don't go ahead with it tbh.
