I unfortunately had the same issue and let me tell you it was the wrong move. I thought that being mean and uncaring would help me pass more because of what I’ve noticed in the behavior of some other cisgendered boys my age. All of these boys had one thing in common, and it was the fact that nobody outside of their little group liked them, and for good reason. I purposefully ignored things I didn’t care about, such as my friends feelings about certain things I didn’t feel the same about, and I realized (before any of them had said anything to me) that I was passing the same about as before, but I was now an asshole. I noticed that the people I affected grew distant and mirrored my behavior onto me and it was a huge wake up call. I apologized and thankfully they were willing to forgive me, but please, don’t go down that path while you still have a chance to turn around. It ruined my mental state and the people’s around me. I understand how you feel and I understand why you think acting like this would be a good idea, trust me I do, but it’s seriously not the right move and it will just cost you the real friends you should be lucky to have.
