Asking for apology not free-speech threat

Asking the groups responsible for recent ads for an apology does not put free speech in danger. This is not a question of free speech at all. There are no consequences for these groups for what they expressed.

If the university threatened to expel those responsible for the fliers and e-mails, then it would be a question of free speech. But to demand an apology is just another exercise of free speech and does not impinge on others' rights to express themselves freely.
