Interesting. Im actually an amateur boxer and may be the most docile person you meet. I obviously dont think its barbaric, theres alot of technique and athleticism involved.
I am super competitive and have always prefered physical sports though, i think as you cant really hide in them (Lacrosse, Ice Hockey, Rugby, GAA)
As for comparing it to watching/following animals tearing each other to shreds, i feel no need to comment.
FYI: found your comments interesting, i am not offended
