So, I want to do some martial arts, for self defense. Ideally one that will be useful without giving me CTE, or any long term bad stuff, even though I feel this is already asking for too much 
I don't live in the U๐๐ so gun related stuff isn't really an option.
I'm somewhat heavy, with a year of experience in lifting, and my cardio is not the best, but I can do long walks (of 1 or 2 hours) before getting tired.
I'm going to move to a bigger city in September, and there's a lot of stuff available, so you can comment on the more niche options.
So yeah, any advice from your experiences is welcome lol
If I had known people started arguing over my post I wouldn't have made it.
Wow can hardly imagine what a heatscore you must be if this is anything other than fantasies. You sound like one of those "castle doctrine" dickheads. I wouldn't go anywhere with you IRL for fear you would escalate to 100% any little thing.
Ive experience "so grievously breach the social contract as to lay your hands on me" many times and in most cases I was able to easily exit the situation by shaking them off and walking away. Could even be some kind of benign mixup.
Since you have internet access, I must conclude this is all posturing because everyone gets touched once in a while out in public and if you actually shot people with such little provocation, you'd be incarcerated.
