Any act that is done unnecessarily to provoke a group of people should be punishable. If a person gets away with doing that, others gonna do the same thing with the mentality of that they can get away with provoking and offending Muslims(or any other groups) so it's going to get worse if those who provoke a group of people on purpose(not only Muslims) can get away from what they are doing.
Insulting one another value's spreads like an infection, if it's not stopped, it's going to get worse. Any person who's not remorseful in spreading hate and offending the values of a person must face its consequences. The consequences which can help make a better place where people with all kinds of values can coexist with one another. If the goal is to make peace between people with all kinds of values, then the only option is to eliminate those who are offending one another's value unnecessarily which means that they were not provoked by anybody and just starting an argument without any purpose just to offend the people and get some attention.
It's up to the administrators to take up my words or not. If they do want to have a non-toxic community then think what I said maybe you implement the rule I am mentioning right here. To have a peaceful or toxic community, is up to the administrators and how they enforce certain rules.
