We have a little thing around here called a “sarcasm tag”.
It’s used when your sarcasm might not be noted.
Indeed, I’ve heard the same argument. I don’t like redistributive socialism, or socialized healthcare, or whatever a lefty thinks will make him feel good about himself,
and his justification is “well, you like having fire departments, police, and public roads don’t you?”
I kind of thought the sarcasm was understood.
