So called religion of peace

Recently Iran has sentenced the popular singer Amir Hossain for blasphemy after he was convicted of insulting Prophet Muhammad. Such incidences have become common in recent times. In 2020, a French teacher namely Samuel Paty was beheaded outside his school by a Muslim extremist for drawing cartoon of Prophet Muhammad and that need was fake as well. And I have seen many Muslims online support such activities saying how Islam is a religion of peace but they are not tolerant of people who insult Muhammad or their religion. These people are still stuck in the stone ages with their horrible ideology.
