The word 'racist' didn't appear until your post. It's a shame we can't discuss obvious language bias without you becoming defensive about imagined sleights.
Favoring a Western lens or English language sources is racist, whether the word was used or not, insofar as it favors white people and the people white people care about. You might disagree with that definition, but it's not like the commenter above is the first person to use it that way.
IMHO the golden years for making friends are the school years, peaking in High School and College. After that it's a desert compared to that oasis.
That said there's a cheat I've heard of for the terminally lonely extravert: Clubs and Volunteering. I haven't tried either myself as I'm an introvert and near hermit happy with my three super-extravert friends that only need to hear from me a couple times a year.
Then there's the ultimate cheat, get married and have kids. Totally worth it, IMHO.
