Thanks! I was commenting about how your squaring up = 50/50 chance of winning is bs. A bigger guy, experienced MMA guy, hardened violent offender, and even an experienced wc guy would have an advantage over a smaller inexperienced guy.
But I agree that squaring up is stupid, I also train from a neutral stance. I also train to take an unassuming hands up stance if things are sketchy. Squaring off is what fighters do, it does give the other guy the advantage to anticipate that an attack is coming. I recommend keeping cool trying to diffuse a situation and if the guy continues or tries to chest bump, let him have it. An MMA guy or boxer is perfectly capable of not squaring up too.
