He's not making a public event of murder or racism. (Sorry, Islam/Muslim is not a race, but a religion).
And it doesn't matter how many calls there have been, until he has received his due process and been convicted, it's all hearsay, and therefore he is innocent.
So you can stop trying to tar him with that brush, unless and until he is convicted. No judge would let you get away with it in the courtroom and you are not going to get away with it here.
