When a carnivore deems it necessary to explain where or how meat is made to a vegetarian/vegan

"I can't believe that farmer gifted sausage made from the piglet those firefighters saved six months ago."
"Well a pig farmer's primary form of trade is through the selling of pork, so why wouldn't he give them sausage?"
"You don't have to meatsplain, I know where pork comes from bro."

moralsplaining 

When someone assumes a moral high ground and holier than though attitude and virtue signalling to add moral lessons to everyday discussions. Always unsolicited.

What I just told you was a true incident that happened in my life. Stop moralsplaining about it as if I made it all up.
