I can only offer my sympathy and understanding. I’ve been the victim of prejudice and harassment and indeed physical assault on many occasions and in many ways. Sadly, there’s nothing about your story that shocks me. The only surprise to me was that there was no one waiting in the parking lot to attack you.
Please don’t let anyone intimidate you into doing anything less than everything you can. And learn self defense. Everyone in this world needs to know how to defend themselves, whether they fit into the main-stream or not.
But believe me, there are a lot of Christians in this country who have no idea what their messiah was really trying to teach. Many Christians believe that it is their duty to convert or kill people who are not Christian.
There were a few people who tried to attack me just to prove that they were tougher than me, but 99% of the times I’ve needed to defend myself it was because my attacker was a Christian and they believed I was evil because of my visible mods.
This makes self defense an even larger need for people who may be targeted by these groups.
Best of luck to you in all that you do.
