Dude there are so many dumb people on this site. They’re reading what they want to read and conflating issues.
You’re simply responding the the statement that free freedom of speech has nothing with the interaction between the girl and the guy because, despite what this guy probably thinks in his head, neither one of them is “the government”. And that changes nothing about the fact that the girl is allowed to flip the guy off.
Perfectly reasonable, if maybe a little pedantic, point to make in response to the comment you replied to.
