That's mean. If you didn't want to be a part of the discussion, then you didn't have to be.
When people say stupid shit like "is fish and chips claimed as a FOOD GROUP because its so popular? Does it ever get really hot and do u go swimming? IDK why, but when i thinnk of britian, i think chilly. Are there beaches?" they need to know I am going to tell them they are fucking stupid.
When someone asks "like for the people who live in Austrailia, do you have the accent? G'DAY MATES? Did you ever eat shark fin soup?" I am going to tell them to GTFO.
It's simple cause and effect. Someone does something unforgivably stupid, I tell them they are stupid.
if you don't want to be made fun of, don't do stupid shit. It's a very simple system.
