Just for clarification, my wise a remark came from your "it's a simple question. Stick with it" remark. Also, I never said you need training, the "IF" was extremely important in my post. If you're thirsty, you need a drink...Is not telling you you need a drink if your not thirsty, see?
Nevertheless, my first response to you completely agrees with this post you just wrote. No, Martin had no justification to punch Zimmerman. If Martin could legally carry, he would have had no justification to pull a firearm either.
So seeing as after a few posts, our understanding is the same relating back to reply #1, I did indeed understand your question.
Speedy healing.
In reply to all the mutual combat posts, I think it is still functional albeit a narrower avenue. One example is an mma gym.
When I started college I trained with mma fighters at the university gym. While I never officially joined his mma gym, we sparred frequently. 99% of those people at the mma gym, male and female, ages 13 and up, had exactly the experience you are talking about. The level of respect towards others was night and day compared to the "girly men" of today. The avenue is there for our society, it's just to physically hard, and we've become so obese as a society.
7 years ago we held a fight night at our co-op house. It was a dry house, not affiliated with the university so we had whatever weapons we wanted in it rooms...and there were plenty. It was in this house I met the mma fighters. Well we set up mats and tiki torches in our side yard, and proceeded with the fights being judged by a professional mma fighter/ref. A police officer rolls up and asks for the president of the house, asks him if we were drinking, and if this was voluntary. No we weren't drinking and it was all voluntary (mutual). Police officer told us to be safe and let all the other officers know what was going on, and we were left alone the rest of the night.
