I said noting about what you should or shouldn't do, but I did point out that your tone was combative. And your reply is that I have bullshit. Well, that really speaks for itself: You're a fair-minded, egalitarian, meritocratic, open- minded fellow until called on the toxicity of your tone. Then you become fully abusive.

Tell me why anyone should expect that you are this way when discussing gender, colour, and stature, but miraculously transform into an open-minded and welcoming person when discussing technical ideas?

I'm open to discovering new things, but my bet is that you're rude and bullying about everything, not just this topic.

One upon a time businesspeople would drink together, because alcohol would lower inhibitions so it would strip away the false friendliness and you could discover what people were really like.

Now we have the internet, and no alcohol is needed for people to drop the pretence of civility.
