Someone else might know of a "definitive guide" (please chime in!), but The A11Y Project is one of my favorite places to start. There are a ton of links over there for things you can read up on, tools to help test a11y, and other places where you can continue your research.
This is a tough one. I've not been really successful in my own experiences. The two best approaches, to me, are the following:
Writing accessible code significantly improves code quality, it's a way to be a better developer
It's the right thing to do. Knowingly not doing it is excluding an entire group of people.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
Great questions!
