I HIGHLY recomend taht all whites take self defense classes.
Not karate, it takes too long.
Shop around watch some classes of the insructors to see if they are what you can deal with. ie. drill instructor type or a different type.
A real good self defense class is usually an hr. to an hr.&.5. lasts about 16 hrs. total.
I’ve taught women this type of course and believe me, when the ladies graduate my class, they know how to defend themselves! And it hurts!
Actually I prefer practicing my 2nd Amendment Constitutional right. It’s quite effective.
