There are ways to open Twitter accounts without really identifying yourself.
And if he keeps his comments reasonable and thoughtful, then he shouldn’t have any problems. If he starts screaming for people to nuke Mecca, then he may have some trouble ;-)
I could, you could. One of 100 students on a class in Berkeley, with an open account made in purpose for this effect, I’m sure he’s not taking his privacy for granted.
The problem is not “reasonable and thoughtful”. The problem is, he can’t speak openly. There will be no criticism; no “islamophobia is a myth” tweets. If they were, newspapers would notice (They already did! That’s why we’re talking now here!), shady people would notice, is he taking the risk?
That happening would be a good thing, mind you. It would be a real impressive class. But how many classes are there about “social repercussions of drawing Mohammed, theory and practice”?
