Think about it this way. There are three types of people who become relevant.
1. The idiot. You have no responsibility to teach them and they aren’t paying you. 9/10 they aren’t even grateful and actively hate you. At best, point them in the direction of a list of half a dozen good starter resources.
2. The attention whore. You’re feeding them. Call them out, laugh, move along.
3. The person who really wants to learn and seems like a good person. You need to know them on the level of friend to ascertain for sure and they’ll be less likely to snipe. Rarer than they seem, #1s and 2s come at you like this. Tease with little tendrils of the big ideas. If they bite – Same advice as #1, if they have questions tell them to save them until after they’ve studied those resources. Give the briefest response possible to each question.
You will preserve your sanity (1/2) and spread the good stuff, people might seek you out for it.
