Sealioning is a type of trolling or harassment that consists of pursuing people with relentless requests for evidence, often tangential or previously addressed, while maintaining a pretense of civility and sincerity, and feigning ignorance of the subject matter.
Whether or not you’re intending to do this your comments do come off a little bit like that. I don’t really like the term that much as people often use it to dismiss any further discussion, but it could be why the other commenters don’t want to chat.
Well the other thing is that it’s very difficult to instantly tell from a pseudonymous internet comment whether the writer is a normal person up for a civilised discussion or a troll just looking to wind people up. And no offence, but you sounded pretty pro-brexit so not unreasonable to suspect you were a troll!
