Yes, and most of it is internet blather, based on nothing at all in the real world.There's prejudice in cycling based on stereotypes and prejudice. I'll leave that to others. It's really not a good look, especially if there's any newbies reading this thread.
I remember years ago I was a member of a club that had some very fit sporty/racy people as well as old trundlers like me. Before the annual club ride to Brighton we were gathering and two bikes next to each other had people looking and talking. One was a brand new Di2 (it was a new thing then) equipped bike, and the other was my 80s Dawes with downtube friction shifters. Both had people ooh-ing and aah-ing.
In the real world cyclists tend to be interested in bikes - all kinds of bikes*. It's only on the internet that you get this "All people who ride green bikes and/or don't wear woollen socks are tossers" or similar rubbish.
* And trikes, come to that.
