I’ll admit that I have never really watched it, but after watching a brief compilation that repeatedly featured bowel humour, I became certain about my disinterest.
I don’t know much else about the show. It started out as something loosely inspired by Back to the Future, and it’s filled with typical ‘adult’ cartoon humour.
I know exactly what you're referring to, and I think it's sad that it seems all Rick and Morty fans have to distance ourselves from that copypasta or risk as being associated as "those type" of fans.
The show had its highlights with some very fun gags and bits, which can probably be attributed to Dan Harmon, who is an incredible writer.
Beyond that, the creator is a disgusting creep, the quality has dropped off significantly, and any love and care the show was initially made with has long since disappeared.
I like it overall but the quality has fallen off and the creator is a creep. Everybody talks about the fan base and that's not entirely unwarranted but I've liked a lot of things with annoying fans so I don't hold that against the show. I think it's still good some gas in the tank for good episodes but in the last season I'd say about half of the episodes were bad and I don't expect that ratio to improve much.
