you're forgetting something really essential: actually having some sort of knowledge, experience or opinions on the topics being discussed so that the discussion could be somewhat interesting. This most often requires you to spend some quality time on hobbies or similar activities and I can tell from personal experience that can be an actual problem.
Someone having trouble holding a conversation doesn't necessarily mean they're retarded and can't speak.
Imagine this situation: you don't watch TV, any kind of shows, any kind of movies, barely listen to music, don't even bother to read the news, never actually go in depth of studying/practicing your hobbies to some sort of an expert level, don't even play fucking video games anymore, etc. How do you act in a conversation with complete strangers who you have no (obvious)
connection to, who don't even live in the same country or even continent as you do, who share no friends or previous experiences with you? 
Personally, I don't see a point in even trying anymore and am planning to rather, sadly, just stop altogether and not bother anymore. It's not the fault of others, it's just that really is no point trying to impose yourself on them and expect them to do all the work. For my situation, my few real life friends are all I have left and it feels like I might as well try to keep that friendship alive despite the obvious clues it's dying, at least we have something in common
Don't be so quick to come to conclusions
also someone end me already
