I'm probably just showing my age, but one reason I could never get into Reddit is it always felt to me like teenagers rehashing the same old debates I had as a teenager on usenet/IRC/whatever. It was never the platform, or anything wrong with the users themselves. It's just that I aged out of the "spend all day arguing with random people on the internet about things" demographic. (Instead, I spend all day arguing with old friends on the internet about things).
