These people wouldn't have rioted, in these scenarios if they weren't religious, I agree with that, however lots of atheists groups, (normally communists) have killed religious leaders as they want to institute state atheism and they will kill any counter revolutionary. There have also been lots of religious leaders/religious people dead because of hatred for religion by atheists and anti-theists.
Yes, and communism is widely panned because of their atrocities. You're pulling a classic "You Too!" fallacy. You're acting as if the atheistic persecution by communists somehow makes religions above criticism because "Atheists did it too!!"
My post still stands.
