I don't feel compelled to sympathize with this dude based on the premise that it took "courage" to ask a random girl out to dinner. Rejection is a part of life. I hope I live long enough to see the day when women, in their interactions with men, fear something as trivial as rejection.
Once I spent an entire year working up the nerve to give a cute boy my number; he never called me. I did not demand a reason why, though I could have since we saw each other frequently enough for several years after. He wasn't into me, so I moved on. Street Corner Bike Dude did not respect my first two answers, and I did not owe him an itemized list of reasons. That list would have started and ended with "You just approached me out of nowhere," which he obviously thought was totally acceptable, so it would not have been effective anyway.
Your implication that I should have nursed his wounded male pride by softening my answer is part of the reason women fear rejection too... but we're afraid of being the rejector. Not only are we trained by our culture to be wary of how men might react to rejection, but if we do flat out say "no," we're told later that we should have handled the situation differently. "No" in all its forms has to be respected without caveat, mitigation, or elaboration.
Saellys, if the guy was pushy I can understand your reaction, and you were within your rights to say no regardless. For what it's worth, I was actually on your side up to this point. But the tone of this statement makes it sound like you relish in giving unqualified, unexplained negative answers for the joy of wounding male pride out of a sense of vengeance. Just saying.
