No it's not. You're not talking about personal anecdotes and leaving it at that. You didn't even mention an assault that you experienced. Did you even say "I got assaulted by someone" at all? No you didn't. If you had, and you had used that experience to explain why you are wary of men you don't know., I would have been sympathetic.

However, you're not talking about a personal experience. You jumped right into making harmful generalizations about men without even offering a personal anecdote. It's harmful in the same way any kind of generalization about a demographic is harmful. That's not my opinion, AI came to the same conclusion.

I'm not personally offended. It frustrates me though. In every other walk of life, bigotry is considered wrong. Some saying "yea, yea, not all men" makes it ok.
