I must be the sweatiest person in the world - it used to bother me when I was nobbut a nipper, but since my kidneys failed it is the best thing that could happen to me! Now, instead of only being able to dream of drinking cold beer, I can actually have one post training (you cant imagine how that feels).
Before I joined a gym (A Harpers joint) I was really worried about what people would think - I have anaemia, so I go very 'white' and end up looking like a very sweaty corpse... not a pretty sight. But nobody there has ever said a thing and they are all very supportive. Nowadays I just dont give a damn what people think of my appearance.
As for people who shout at you when you are out etc, I just file them under "fat ignorant slobs who are going to die young from painful conditions" and then forget them.
Sweat on!
