i think its valid, at what point does wearing lycra become offensive? Different people have different tolerances.
Some people would say any lycra is offensive, i guess i am sickened (maybe thats too strong) to see roly polys in lycra. You have to earn the right, you cant just go buy some shorts then go riding in it. You should have to put the miles in first, in the winter too, commute in rain, snow and wind, ride in the mud, hone yourself on the anvil of the bike!
In summary, go fatties, ride the, erm gentle breeze, but for gods sake, no lycra. And before you say im being fattist, im really not fatist. I think you’ll find you are fattist!
