A headline compared ultimate fighting to cockfighting [“The Civilized Brute,” July 15]. The athletes who engage in ultimate fighting are valiant and civilized. They mutually agree to participate in a very rugged and perilous sport. Conversely, cockfighting is a heinous atrocity staged by uncivilized humans who derive pleasure from watching cruelly exploited and mistreated birds painfully lacerating one another in an unsightly scene of bloodshed and carnage. Most ultimate fighters are humane people in contrast to the inhumane criminals who orchestrate deadly cockfights.
