Exactly how does an image cause a disruption? I would think people cause disruptions; for instance, people who behave rudely when they encounter free speech they don’t agree with.
Otherwise, by the logic, you’d have to ban pretty girls in tight little skirts.
Heck, if it really is a disruption, why can’t someone just say, as did the mayor of Baltimore, to just give them room to destroy (someone’s little perpetually offended feelings)?
