Letter: Men need vaccine against aggression

A bench-clearing brawl broke out during a charity hockey game between New York City police and firefighters on Sunday, April 6, 2014, at the Nassau Coliseum in Uniondale.
Let's face it: Men fight and make wars because they were given an overdose of testosterone ["NYPD-FDNY game turns into ice brawl," News, April 7]. They were given the hormone to ensure procreation, but when the procreation gig is done, they still have too much, so they ruin life for everyone else on the planet.
A good inoculation is all that is needed here.
