Taekwondo is a joke, you learn absolutely nothing that could ever be applied to an actual fight, all their graceful and awe inspiring movements are impractical and provide little to no stopping power, they are also useless against combatants in close range.
Not to mention most of the Taekwondo people I have personal experience with are arrogant jerks right out of the gate or extremely cold and tense people.
I was at a KSDI seminar, the man who was giving the seminar made this opening speech: 'I practiced Taekwondo for 40 years before I realized it was bull****', you would all be wise to recognize the same.
First degree blackbelt here, with 8 years of TKD and 2 of Muay Thai and Jiujutsu.
You should put your money where your mouth is, because like all martial arts its about the teacher and about how much work you put into becoming a good fighter. You become a better fighter by fighting, period. Not by practicing shadow movements all day. It doesn't matter the Martial Art you learn. TKD has a ton of very useful and well-rounded tools for fighting, you just gotta learn to apply them.
Don't believe me?
Look up Kwonkicker on youtube, or Brendan Foster. Both are mean as **** fighters and both specialize in TKD. Foster's won several MMA tournaments and the like and has been featured in a couple shows.
MA is about learning your style and learning to compensate for its weaknesses. ALL styles have weaknesses. The idiots who spout that MT, or Boxing are THE BEST. Are morons who have never bothered to train outside of their keyboard, and think they are pro-as-**** fighters because they watch UFC.
