Two things and I'm probably out:
This conversation just shows how stupid it is to try to classify cyclists as serious and non-serious. To be honest, substituting the word "mediocre" is even worse. Y'all are doing a whole bunch of No True Scotsman stuff here and there's no way to do it without sounding like a snob because, basically, it's snobbery.
Second, I find it hilarious when people will say something about how bad a category of bike is and then accuse people who defend their use of the particular kind of bike of trolling or being argumentative. When you post an attack on a category of bikes, you are quite clearly telling people that like the category that they are wrong. Don't do that if you don't want an argument.
