No, the guy who burned the Quaran does not deserve to be beaten up. It was clearly a controversial and provocative thing to do (and I don't agree with it at all), but it does not deserve violence.
To suggest he deserved a beating, is a worrying precedent, which means a vigilante society where we it's 'justifiable' to hurt those who offend us.
I had an argument on FB with someone who is an interfaith representative for a non-mainstream religion (that's not really treated as a religion), and one that would not be tolerated in a Muslim country.
I said that the beheading of Samuel Paty in France. Paty, if you recall, was the teacher who was giving a lesson on freedom of expression and allegedly showed students the 2012 cartoons of Mohammed from Charlie Hebdo.
This 'inter-faith' person, said that the Paty was deliberately provocative and it's not surprising that he was murdered. He said that Western countries must realise that some will act with violence if their prophet was ridiculed and we should accept that and not do things that cause others to behave violently.
He called me a fascist when I said that in a secular country, no religion should be held in such regard, that teaching about the murders of cartoon employees would be murdered for digressions.
He preaches 'be kind' and sees himself as superior for his inclusive thoughts, which means apologising for murderers and blaming the victims. TWAT!
I don't believe in burning books, but we SHOULD be allowed to criticise and mock the beliefs of others, without violence being justified. This will never happen of course.
