@AliAta I think it's important for people to have debates, even to criticise - arguing is a great British tradition, after all, and there are many places around the world where people don't have that freedom to disagree and debate.
There is, however, a difference between reasoned debate and personal attacks, between discussion and stereotyping, between saying "I disagree with this thing" and "I disagree with your existence".
Things are said about Muslims and affiliated cultures, both online and in real life, that would not be acceptable if they were said about any other group of people. For example, in the context of making fun of / minimising the Iranian attack on Israel, someone said that it wasn't a big deal because the injured child was "only a Druze" (the Druze faith and culture branched off from Ismailism). That's a child's life being dismissed on account of her ethnicity and faith. That's not ok.
The physical and verbal abuse people receive from others due to ethnicity and faith should always be considered unacceptable, whether directed at a Muslim or a Christian or a Jew or anyone else.
I'm happy to debate, discuss, criticise (heck, there's plenty to criticise in many faiths and cultures), but I am concerned about the rise in actual hatred and discrimination people from minority groups (including Muslims!) are experiencing.
