If you're concerned with contributing to the gene-pool, you want to make yourself an attractive partner. That doesn't mean you have to be strong, it just means you should take pride in your body and what you do. Walking around with a lead pipe and a desire to find an excuse to use it on someone stronger than you makes you a deranged lunatic. Nobody will want to be around you. You aren't impressive, anyone can win a fight with that kind of an advantage. You just look like a weak loser consumed with resentment.
