The argument that phones are banned from venues because they are disruptive is disingenuous, because far more disruptive things are not banned; or rather, the bans are not enforced. For example, I find it infinitely more disruptive to have people vaping at shows, and yet I have never seen people have to give up their vapes when attending a stand-up show, or ever be made to leave for vaping, for that matter.
As for anger about comedians being offensive, not at all. On the contrary, I think stand-up comedians have a duty to be offensive and push boundaries. I just think it's pathetic and cowardly to try to prevent people from recording those incidents.
