I think the problem really stems from the anti-cyclist-cyclists that frequent this forum. As a result, some posters here are stridently pro-cyclist, see the thread I titled,
"The-mysterious-pro-cycling-anti-bad-motorist-bias-of-BF"
I don't see anything particularly wrong with being overly pro-cyclist. Someone's gotta do it.
In general, however, I do think this forum is net negative for cycling. Too much bickering, anklebiting, and trolling
