And how would you answer someone who says if you fight to protect your life that's cool but if you fight for fun you're a f**king animal. ??
First I have to ask what that has to do with hunting? The intention of sports combat is not to kill.
But, if you wanna go off topic, I would simply say that fighting is a relatively safe sport that two willing participants engage in. There is no innocent victim who has no choice or understanding of the situation.
A sanctioned mma fight takes place with two willing individuals who both stand to profit from the match and in the process entertain us. I'm not sure how that is comparable to some guy with a high powered rifle with a scope, and other technologies that making the playing field ridiculously imbalanced, sniping off a deer for shits to make himself feel powerful.
And it's not that I think people who do it are animals. Animals would eat what they kill. I think it is disgusting to derive pleasure by taking the life away from something just to hang it on your wall.
I also think it is selfish to kill something you clearly find beautiful enough to display and therefor rob others the chance of ever seeing it alive.
I'll say it again, though: if you hunt and eat what you kill I fully respect that. Anyone who eats meat but is unwilling to see an animal die for that same meat is a hypocrite.
