Your ignorance and irrational antipathy about reddit is well established.
There is a wealth of good information in there about every conceivable subject. The hobbyist subreddits (not all of them) are usually fantastic and welcoming to beginners. So are the support groups for people with various rare disorders. Ditto for the ones about local news and happenings (in my maybe limited experience). One those ones people definitely know each other and have meetups and are generally well moderated.
The larger subreddits like /politics are certainly like that but that is a small fraction of reddit.
