I used to visit communities like you did, then I took an arrow in the knee.
But no, seriously, if you don't like the how people are talking, don't bother going there. I don't know people who use Steam's community hubs for actual community. I see them getting used for info/joke sharing about their given games, but not for social bonding. Personally, I like the guides. Sometimes I search the discussions for a piece of information on an issue that I'm hoping someone else has already encountered and worked around. That's about it.
That said, I generally don't mind that people make memes. If it makes them happy, then good for them! If other people get a chuckle, that's even better. For me -- and like my opening line -- any amusement quickly turns to eye rolls as the same things get repeated over and over and were never very funny from the start.
