There certainly are many victims of the patriarchy, many of them like you, many more of them not. If you think I support that in any way, then you've grossly misunderstood my statement. Your personal attack at merely reading an opinion slightly different from your own is one of the greatest problems in our "liberal" society these days. There's a reason why opinions like this can not be openly shared, even in a safe space like this, at the risk of being attacked.
You don't get it, man. You are attacking a fundamental piece of my identity and expecting me to be "nice" about it, as if parts of myself that I know unequivocally (and that have been backed up by years of scientific studies) are something that you can just debate without consequence. As to why I think you support it, the title of this post is "Shake it up. Offer up one somewhat unpopular opinion that you hold.", emphasis mine, of course. So if you don't hold the opinion that trans women are not women and that trans men aren't men, then why did you say it? Unless you don't understand that my being a "victim of the patriarchy" is a direct result of you holding that opinion, I can't see why you're surprised that I "misunderstood" your statement.
