It's Lemmy, you're anonymous, of course I don't know shit about you. You may be the most wonderful person in real life, but I'll only respond to what you say here. So this defense is utter bullshit. Don't post on anonymous forums and then complain that people don't know anything about you before replying to your comments. That's the whole point of anonymous forums. That people only reply to what you explicitly post, and nothing else.
Also, I'd suggest not taking any of this personally. None of us are properly represented online. All this criticism is just about your opinion on this one topic, and do not reflect our (at least mine) opinion about you as a person. (Because we have no idea about you as a person.)
