I know this thread is a bit old but the OP's question really resonates with me. I'm in the UK and I don't really fear physical assault, though it could happen, what seems much more likely is verbal abuse or taunting. I imagine the following scenario.
I'm walking down the street feeling a million dollars in a favourite frock. Some neanderthall shouts from across the street calling "There's a bloke in a dress!, hey look everyone! A >-bleeped-<! hahaha!"
I know I would crumble into dust at this. Here that would be a hate crime and the guy could get in serious trouble for doing that but the chances of me even reporting it would be about zero. I would run as fast as I could to a dark hole and never come out again.
The general advice on this is all great, baby steps, be in company, stick to the more accepting neighborhoods, and it gets easier the more you do it. But... taking that first step is absolutely terrifying to those of us who have no-one to hold our hands at the beginning. It would be terrifying to me even with support.
I have nothing but admiration and respect for the people who have overcome this, especially if they did it alone. For me, just thinking about taking that first step, alone, in public, makes my blood run cold with fear and I feel a little sick.
I've read a few threads on handling this sort of thing and I know what we "should" do. When I imagine the reality of it, I know I couldn't cope.
I know this doesn't really add to the discussion other than to perhaps illustrate that we as a group might be more visible if all the people like me didn't fear being ourselves in public.
