I do think that legislation should be avoided if it's not necessary. If complaining or boycotting gets the job done, then that should be the first option. I'll never understand people who think we shouldn't complain or boycott. Surely this is just an exercise of one's right to free association? (Not saying you're objecting to them. But a lot of people seem to think that it's somehow wrong.)

On the other hand, if an issue is important and legislation can get the job done, we shouldn't shy away from it. To describe someone as "a perverse sadist" for wanting to legislate pseudonyms on social networks is bonkers.
