I wouldn't have known what iirc meant, either.
No, you have a point. I know I've never lashed out at anyone here about something irl (in real life)
I used to have a pen-pal (email) from Scotland who used to laugh at me because I was so political, but let someone else put the US down and he said I was the Patriotic Princess. It's like someone picking on your brother or sister, I guess.
