again i don't see how MMA/Boxing/Kickboxing are inherently more "violence" or less 'honorable" than other combat sports/ martial arts.
trash talk and all that stuff are caused by fighters or promotion, it has nothing to do with sports/martial arts itself.
now if say that the promoter in sports such as Boxing/Kickboxing/MMA created the culture that promote trash talking and bad behaviour, i probably would agree with you.
also, i never said martial art are only fight sports, there are many martial arts that focuses on self defense/art/self improvement, and i respect and admire all of them.
MMA is basically the result of each different martial art cross training and competing with each other.
You're misinterpreting what I'm saying. I am not saying the sport itself is more violent or less honorable. I am saying the mentality and culture around it is different. The focus on respect, tradition and ritual is a lot stronger in martial arts than it is in combat/fight sports like MMA and Boxing where the only goal is to fight and make money and where there is not necessarily that much emphasis on teaching and learning respect. This clearly comes across when you see the attitude of a lot of fighters before and after their fights, sometimes even during.
Trash talk and violent acts are caused by the fighters as you say, and those fighters represent the sport they are in. The attitude you see from them outside of the ring when trash talking, attacking buses, attacking the opponent's coaches, attacking the referee, not letting go of chokes, striking the opponent too many times when they're already out, and so on are all actions by the fighters which are associated to the sport they represent.
We are not just talking isolated cases either, they are literally long youtube videos of many different clips showing MMA fighters or boxers attacking referees, or starting brawls at press conferences and sport events, and so on.
Now I challenge you to find the same type of content from Stadium Muay Thai, a combat sport (AND martial art) which has existed for much longer than MMA and has more fights per week than the UFC does in a month. It is also a professional combat sport with paid athletes, promoters, etc.
You missed my point about martial arts having more than "fighting". What I meant by that is not the other physical elements of the training like self-defence and so on but the moral values and discipline that goes with it - something I've not seen being focused on when going to Boxing or MMA gyms. It's a different mindset with different objectives in mind.
And of course the fact that the promoters and the culture encourage fighters to trash talk and act badly to get viewers excited for the fights definitely doesn't help either.
MMA is just a fight sport with quite an open ruleset. It's not the be it all of martial arts like you seem to make it sound.
