It's a good question, but it does have an answer: violence. When members of a community do violence, especially generalized violence, it seeds terror in the population. It's not fair that the entire community is blamed for the actions of a few; in an ideal world we'd be able to understand that distinction. But from all the history I've read, that's not how humans work. We make snap judgements, generalize and approximate about large groups based on anecdotal evidence. (It probably doesn't help that "incel" connotes "terror cell".)
