Lol. I don’t know where the hate comes from, but your post seems pretty accurate to me. There are rude, liberal bicyclists and rude Freepers but they aren’t the majority either way.
We live near Seattle, so we have a lot of acquaintances who are extremely liberal. Many of my cycling friends are liberals but some of them are the most conservative people we know. I actually ended up on one of our local conservative talk radio shows when they had a segment where nearly all of the callers were trashing cyclists. It was after the radical cycling group Critical Mass had staged some type of traffic disruption and really gotten people angry about cyclists.
I had a productive discussion with the host and he actually invited me to speak with him again the following day and help respond to other callers. It was so long ago that I have forgotten who it was now, but he said that I helped change his opinion somewhat and a few others seemed to respond to what I was saying when they were reminded that not all cyclists were lefty nut jobs.
