Sorry you experienced that. I had not heard of that meme before reading that thread you linked. I'll say as an male-presenting person, it definitely doesn't feel good to have people assume that you are inherently dangerous for reasons that are out of your control. That's where the instinct to minimize comes from, I think.

But that's how it is, unfortunately. That's the consequence of living under patriarchy, and if a guy doesn't like it then they should assist in dismantling it rather than trying to dismiss its harms.
