In fairness you probably attract more of that sort of thing than 99% of people. I mean, if you're going to act so aggressively alpha, you're going to get attacked often. So your view might be a bit skewed here.
I can say with a fair amount of confidence that Zed's fully aware of this effect, and is doing what he does intentionally. He has informative content, but also knows how to push precisely the right buttons. It's often entertaining, but the abasive style is also a brilliant and effective form of self-promotion. (Think Donald Trump or Rush Limbaugh.) He knows precisely what buttons to push to get a reaction, and (as far as I can tell) enjoys himself immensely. It's great to watch if you like to see flames written to people that take themselves too seriously.
So I don't think you're telling him anything new here. If you sit down at a table and don't know who the sucker is...
