I’ve posted previously this year about the growing trend toward disrupting and shouting down political opponents’ rallies and events. It’s worth mentioning that much of the disruption, notably from activists claiming to speak in the name of the group Black Lives Matter, is actually more against political allies than against opponents. On Sunday BLM’s local chapter disrupted Toronto’s annual gay pride celebration — which trustingly had invited BLM to lead the celebration — with a list of demands including no longer allowing law enforcement to have floats in the parade. I’ve compiled a new Storify telling what happened next. More: Jamie Kirchick, L.A. Times.
