It's a pretty obvious way to think about it, but I thought it might be the sort of obvious that was still worth making explicit:
Imagine a right-wing advocacy group is very upset about a mosque, because it thinks one of the imams is a supporter of anti-American Islamic extremism.
They go to the mosque in the middle of services, and start shouting "the time for Judgment had come," blowing whistles, chanting "Muslim Extremists Out!," "Remember 9/11!," and the like. They approach the imam and congregants in a way that some perceive as menacing, and loudly berate the imam with questions about jihadism and Muslims wanting to implement Sharia.
