Well, as you asked, and in the interests of cultivating a little controversy, I think many sports people are base primate mentality at best, obsessed with chest beating at anything they can, invariably to the detriment of their fellow man, for whom they have little compassion or respect. It's survival of the fittest and anyone not up to the physical mark is treated with derision and contempt.
Ergo, drinking pint boots after rugby matches at my old college. Great till someone died. Bright thinking lads.
Having said which, my one regret in life is that I didn't "find" sport before 43 years old.
Socially, whilst I enjoy a post ride cheeseburger and a chat, party time is not my thang. Neither are team games and comparing your dicks in the shower afterwards.
Again, having said which, the cameraderie in an event such as Southwater tri, where you each do your own tri, but for a team, is orsum and am proud to be a part of it.
So, having probably pissed off the few people that DO tolerate me from time to time, I'll sit back and dodge the rotten eggs!
