First of all, I'm sorry that this happened to you. I've never met a cop I liked, aside from my grrlfriend, but she's no longer a cop, lol. In my experience, male cops tend to be very stereotypically male and very anti-queer. It may just be that I grew up in PA and then moved to a town mostly populated by rednecks, but I never felt safe around cops, either as a grrl or a queer person. I hate the way they treat my grrlfriend for being trans and I hate the "cops are above the law" attitude alot of them seem to have.
Honestly, in your place, I would have felt both angry and threatened. Probably more threatened at the time and angry later. Cops have the power to make our lives very difficult without being questioned by most people and bigots with badges are very dangerous.
