I was mostly referring to the violent crimes that happen all over the world. To a good portion of people there is a really good chance that you're mugged while on the street.
I never stated it wasn't violent, I only stated that it wasn't savage, there's a big difference. There's an incredible amount of violent things in this world and it doesn't have to be physical violence to be considered violence.
Going off other people's research into the matter, it does not make a person more violent if they participate, specifically, in boxing. In fact what does happen is a disciplining effect which helps people who box control aggression. People without an outlet for their aggression are more dangerous than people with an outlet, and people who are trained with dealing with aggression. Boxing also helps humbles the boxer, other than the health concerns there's more benefits to practicing sports like boxing, which is why they(martial arts in general) were primarily invented in the first place.
Chess and Boxing, Chess is a hugely complex game that uses the mind and a lot of self control, same with boxing. Just the fact they combined a supposedly "savage" sport with a sport considered to be the least "savage" is quite honestly cool.
Hence there's a heck of a lot of preconceptions to a sport like boxing, and if no one enjoyed it then it really wouldn't be around.
