Of course, when people become their own "gods", something that is in my opinion pretty much the norm, we get to make up our own morals and rules for everything. HighlandHomie, for example, is not all that bashful about saying adults putting kids into a fight ring are committing "criminal child abuse". Might be some judges who would say as much. even without a specific legislative definition to rule on.
Same guys want government to use force on every issue to secure compliance with their laws, actually, even though they might not be all that ready to understand themselves in that light.
In watching the trailer, what I saw was training for self-defense in some aspects, and at least one kind of sport that society has traditionally accepted. People who don't like this seem to be on the same page with the folks who object to kids playing dodge ball, philosophically speaking. It's the mindset that "the government", through an infinity of supposedly "good laws" and an absolutely adequate police force with sufficient arms, should make sure nothing goes down in this world that isn't not "approved" by the truly enlightened elite intellects among us.
I picked out the comment from one of the fighting pastors that much of Christianity has feminized men to the extent it is a definite problem.
Men need to be competent to defend themselves, their families, and their liberties against any threat, including "do-gooder" liberals who are just out of touch with reality and living some kind of tyrannical fantasy of their own, and who do in fact employ, at other peoples' expense, force to do so.
