Predator vs. Alien…
Anyone contemplating a physical attack against any group or their property in society, regardless of the dangers that group poses to the continued health of society, deserves to be punished to the full extent of the law. Whether they be Islam 101’rs, Marxist, Fascist socialists, they deserve the same protection as anyone else.
That said, these totalitarians also deserve to be challenged and confronted with proper, rational verbal argumentation whenever possible. In order to have a viable, liberal (classical sense of the word) representative democracy, you have to allow the free exchange of ideas and challenges/criticism to those ideas.
Unfortunately, Islam has been allowed to carve out a protected sphere for itself, where “having one’s feelings hurt” is akin to threatening with a loaded weapon.
