Please look at that trannies is a plural term for more then one transexual it is not a harmful or disrespectful term.
He kinda has a point it is just the plural way of saying transsexual yes he could of said many other things and yes it was probably wrong of him to do but this is hardly "mass" since he said it once and tbh it's not exactly hugely offensive if u understand the word correctly it just sounds bad.
Unban this man he said he is sorry.
