not to frack with transpeople? It's not a good idea to get someone pissed off at you who not only has a little more strength than the average cis female, but is an estrogen based lifeform to boot.
You also don't know how much bull feces that transperson may have gone through just trying to get through her day.
Your attempt to make fun of them or disrespect them to prop up your own flagging self esteem may be the last straw that sets the transperson off and the next thing you know they're either reading you like a cheap novel, pulling out a can of whoop ass with your name on it or are doing both at the same time...
If you think Moni's sellin' you woof tickets on that, check out this latest video of some cis person who got more than he bargained for when he disrespected a transwoman minding her own business in the New York City subway system tunnels.
