Sorry thats absolutely sh*t for your aunt. I won't apologise for the swear cos some people make me so angry at times. Wether they're drunk, idiotic, ignorant or just plain nasty, theres no excuse for such disgusting behaviour.
I really feel for your aunt. Especially at an early stage of her transistion, when shes still learning about herself and coming to grips with a whole new side to her, the reprehensible actions of some idiots have damaged her new found self confidence and belief.
RE: The Court, hopefully the people in the bar, or CCTV will back her up - that she was an unwilling victim in what is (basically) a hate-crime. From personal experience, going to court is quite taxing but hopefully if she thinks of it as an ending to a appaling incident, then maybe she can move on from this and regain her confidence and belief in humanity.
I know these words mean f***-all to her at this stage, but life goes on and she shouldnt let the actions of a bunch of morons define who she is.
