Most of the stuff is funny. But, some of it is offered (and often taken) seriously. I take particular objection to:
It’s all about the bike
Really? This isn't
SCCA. You can't just buy a fast bike like you can buy a fast car and be competitive.
If you are out riding in bad weather, it means you are a badass. Period.
Even a dog knows when to come in out of the rain. Your legs don't know if you are indoors warm and comfy or outdoors in the cold sleet. But, your skin and lungs do.
I don't mind riding in summer showers on training rides. But, not in the Fall, Winter, or Spring. Screw that.
Spare tubes, multi-tools and repair kits should be stored in jersey pockets.
Pfffft. So you can have all of that crap sloshing around your back inside of your jersey pockets? Whatever.
Slam your stem down.
Whatever.
Do what fits best...not what looks best. Don't be the guy on the bad-ass bike limping in 30 minutes behind everyone else.
Ditch the washer-nut and valve-stem cap.
The valve cap maybe, but the washer nut is functional. It serves two important functions. 1) It keeps the valve stem from recessing into the tire when pumping a tire that has little pressure. 2) It keeps the valve stem from tap, tap, tapping the edge of the rim if it ever becomes off-center. If you've ever had this happen on a ride, it will drive you nuts. "tap tap tap tap tap tap tap tap tap tap ..." for 2-3 hours.
