Guns cannot be carried legally by the vast majority of crossdressers in the world.
I canot legally carry concealed a gun, a knife, a sword (mentioned only because I am good with one and they can be concealed in canes), a taser or mace. All concealed weapons are strictly illegal for civilians in my state.
The best I am legally allowed to do is carry a personal alarm and while I can poke a key through my fingers to protect my knuckles and inflict greater damage assuming I have time to do that I can then possibly be charged for doing so!
Now a crossdressing child was murdered with a gun in his classroom in the USA within a week of my birthday this year. Some transpeople have been murdered within their own homes.
Even the 'safest' places can be unsafe. Not everyone assaulted for being transgendered had a choice of walking away or avoiding a fight.
The gun issue is an option for only a tiny minority of crossdressers. What about the rest of us?
So as guns aren't the answer for most people what is? As nowhere is totally safe what then? As you can't always walk away what then?
How about treating the cause rather than the symptoms?
