Isn't this wish rather selfish as well? Rather than spending time, becoming a contributor yourself and effectively showing them a better way, you want them to disappear.

It is. Have you done that? Does it work?

Becoming the example that people want to emulate? Yes, it does work, but it's a lot harder. The key is to do it in little increments everyday. The more influence you have, the more you'll be able to sway a person's opinion. Growing this organically is the challenge.

This does happen a bunch. I was always dreading asking question in #nginx back in the day, and #bash could be pretty rough too, but you learn to grow a thick skin.

Well #golang is a good test for thick skin. I thought mine was thick, but no.
