I think every member of society is entitled to a minimum level of respect. Some groups of people in society face more discrimination and harassment than others due to some common attribute they have, and my opinion is that they should be legally protected from that.

You are in your rights to think Islam is a cancer, you are free to protest Islam publicly, whenever and wherever. The difference is that your critique of Islam is legal and valid, but you can't target Muslims. Certain actions combined with a place and time can turn valid critique into incitement.
