i have seen the violence first hand. I worked clubs in melbourne for the better part of 30 years as a second job. worked the odd few gay/gay friendly places, mostly because there was rarely trouble and the money is actually usually better.
So in the clubs where they arent outright gaybar type places its more a case of there might be the odd few gays and maybe occasional tranny. At one of these places there was a tranny that was a regular. they never tried to hide the fact they were trans and weren't on a soapbox just for all intents and purposes another regular patron. Anyhoo one night some bloke was all over them like white on rice keen as mustard. was practically to the point of trying to bang it in the toilets. And then his mates showed up, and he went from trying to get laid to 'youre a fucken freak' etc etc and it escalated. me anbd my mate that were working the door got it sorted quickly enough but I'll fucken guarantee that person would have ended up in hospital in a coma if it wasn't for us. I've seen similar stuff happen along the same lines, I won;t bore you with details, it's all the same general story.
if they aren't up front about being trans before they get beyond a PG rating with some guy, I think they're putting their own head in a noose. I'm not justifying the violence but I live in reality not happy purple sky land where unicorns fly over rainbows and shit out glitter
Don't get me wrong theres more than a few dickheads that are looking to be victims and anything anybody says to them , inniocent or otherwise and they have to make out it was about being trans. They are Khunts to deal with at the door too. And I've met no shortage of trannys that were completely batshit crazy over the years (I';ve often joked that that might actually be proof that they are infact real women!). But by and large if they (and this goes for all humanity) aren't getting in peoples faces I just don't give enough of a fuck to care. Now if they are grooming kids or anything like that, I'll supply the fuel for the flamethrowers, even the flamethrowers themselves, make no mistake.
But short version - the violence tends to come from guys that know they are trans and secretly want to fuck them and then panic at being found out.
