I've been thinking a lot about what happened, but the details I've been able to glean are rather thin. I'm still not clear on what they did to you. I read your forwarded message, and it seems totally legit to be cautious and stay away from this fucked up santa cruz scene for a while. Purchasing a gun is, of course, your prerogative and all, but I don't think you have anything to be paranoid about where you're at now. Whatever threats you're still receiving are probably just people venting anger in fucked up ways.
I was talking with xxxxx about several recent "politicizations" of personal relationships: why these things are happening in NY and SC, etc. I'm sure it's no consolation to you, but I think understanding these dynamics might make it less senseless. In my own opinion, it seems like a lot of very pretty and very young girls were involved in the political actions of this past year. These girls tended to gravitate towards men who they thought were respected in the milieu -- yourself and others -- and probably became sexually involved because they calculated that they could gain some sort of position in the group, however unconscious such calculations may have been. It's a very normal thing and a much larger social phenomenon than the narrow confines of Santa Cruz. However, in the current context, many of these girls probably don't have much experience with that kind of sexual promiscuity, and it backfired because it didn't actually improve their standing in the group. It was probably more neutral than anything else. Some combination of naivety, misplaced anger and vague notions of patriarchal oppression led them to scapegoat members of the group who are easy to single out: you, Evan, perhaps others.
None of this means that what people have done isn't fucked up. So I don't want to imply that these actions are in any way "excusable." But they do seem rather explainable. I think you got caught in the cross-hairs of a politically charged, female "coming of age" moment. But again, my information is pretty limited. So anything you can share with me about the events would help me to formulate an effective response to the situation.
Stay well, buddy.
