That’s awful, awful.
I was too late seeing your earlier post to feel I could add much in the way of words of consolation, but I’ll try now:
From this distance, in the light of everything else you’ve said about about Claremont, this sounds like the act of a few who know they’re in the minority, who know they’ve lost the debate in your community, and are lashing out at the nearest available target as a way of convincing themselves that they still have power, even if it’s only destructive.
Obviously it’s upsetting, and it’s hard to know how to stop it from happening again. But it doesn’t define your community; it only defines the disaffected in your community.
