The proof is in your hostile attitude toward her.

Her post is about how she felt profoundly unwelcome in the FreeBSD community. Your response is not a counter-argument to her feeling unwelcome. As far as I can tell, your response is, "Randi did bad things." That's a non-sequitur. It's not a response to her feelings of being made to feel unwelcome.

If you had a germane response, I am guessing it would be, "Randi should feel unwelcome, because she is not a good person." If that's your response, you're not actually disagreeing with her. She said she felt unwelcome, you're basically saying, "Good. Yes. That's a good result."
