In this case I think it is beneficial to have a dedicated community where the expectation is that young people, while not excluded, are not going to generally be the ones participating in discussions. It’s true that for now Lemmy has a relatively small user base, and that it’s skewed toward older and male users, but that won’t always be these case.

A quick search also shows at least 9 active “ask” communities besides the generic AskLemmy one. I don’t think it’s too much a stretch to have one dedicated to older men politely talking to one another and giving advice to themselves and others from an older male perspetive. I’m finding it difficult to explain myself, but the vibe is just totally different on the AskMenOver30 subreddit than general “ask” subs. It’s more mature and frank while also being curtious and free from politics, conspiracies, and toxic masculinity. I would much rather be subscribed to and participate in a narrowly focused self-selected community like that then a generic AskLemmy community.
