I'm quite glad that you find missing the entire point fascinating.
Yes, I concede that you're right. You can certainly use lemmy/kbin only as a forum. You could certainly use Reddit as your "chat" platform too.
My entire point was that this person asked a question about trying to aggregate content; your toxic response was instead to talk about how terrible wanting that is and that they should just not want the thing that they were happy with. This is the type of high-quality "discussions" one can expect to bubble to the top in these silos.
