Going to try to say this at greater length to avoid misintepretations.

When you said that "You can tell nerds are oppressed in our society because it's so hard to find positive coverage of Star Wars", I interpreted this as a sarcastic way of saying that since Star Wars was popular, that implied nerds could not be oppressed. The argument has an implicit premise of "If a group has a popular cultural product, they cannot be oppressed".

I was saying the implicit premise was obviously false, because groups that we both agree are oppressed, eg black people, also have popular cultural products. So the fact that nerds have Star Wars says nothing about whether they're oppressed or not.

I was not taking any stand on the object-level question of whether or not nerds are oppressed. If you ask me, I would say that "oppression" is too broad-grained a category to use here, but that certainly they face a lot of problems, bullying, harassment, and end up with a lot of issues and self-esteem issues, to the point where people should be careful about contributing to that. But that has nothing to do with why I complained about your argument. I complained about it because I thought its form (rather than its content) was silly.

I'm pretty upset that you retweeted me out of context in a way that makes me look stupid and if upon thinking about it further you decide that wasn't what I meant, I would appreciate you deleting that tweet.
