When it's about bikes. People foam at the mouth in those comment sections. Soo many options. I could go all self-righteous bicyclist, or I could talk about how many guns I've got in my glove compartment*, or I could complain about how every cyclist runs red lights ALL THE TIEM (to be fair, that comment wouldn't stand out). Bragging about critical mass meetings would also be a good one. Soo many options.
*that was seriously one of the most fucked up comments I read on the FP a while ago. The dude talked about shooting people for touching his car. The fuck dude.
