Um... well, personally, I find muscles a turn-off, but other things a turn-on, so there's always individual variation. As for those two women, I don't know whether this actually happened or not/the way you say it did, or not, but if it did, why let a couple of assholes ruin your day? I once walked to a festival and half-way there, a guy in the passenger side of a convertible threw a (full) liter-bottle of water at me as they sped by. It was heavy and it hit my shoulder quite hard, and my first instinct was to feel furious. But what can you really do in that situation? Salami has a point: there isn't much you can do, so just focus on your own peace of mind in that kind of situation.
I never saw them again - there were no lights immediately up ahead for them to stop at - and frankly, I'd prefer not to see anyone like that again. It's annoying, but there are assholes in the world. Focus on the awesome people, dude.
As for going out for a run - good for you! But yeah, maybe go in the evening. No worries.
@2085034: Yeah, my bullshit sensor's going off at the "you're not hot" comment. I'm not sure if I'd throw it out completely as something that definitely didn't happen, but these incels tend to get a disproportionate number of unsolicited comments about how not-up-to-par they are. My best guess is that if it did happen, they might have said something like, "Aren't you hot?" as in, "Dude, it's the middle of the day and you're out running? Surely you must be boiling alive!"
@Dr. Hugo Strange: They certainly ease themselves into the situation until they find it hard to see things another way, but that's just the point: THEY get THEMSELVES into this situation. They are therefore responsible for the fact that they're in it, and can take whatever negative reaction they damn well get. People overcome adversity all the time; it's possible, and I'm living proof of that. And I don't believe it's a psychiatric condition. I firmly believe they have talked themselves into this (or allowed others to talk them into it). Responsibility for their life situation rests firmly on their shoulders.
"I may well remind you all that young men in their teens and even into their early to mid twenties are often hungry for self image" I may well remind YOU that young women are subject to the same desire for self-image. We may be subject to different pressures and usually come to different solutions to the young men you're talking about, but we're made absolutely aware that it's our responsibility, even our fault, when we become self-conscious.
