¯\_(ツ)_/¯
There is always somebody offended by something. My advice is to get over it. Life's too short to piss and moan about what someone else may be doing that offends you. Nobody really cares what offends someone else, I sure as hell don't. But hey if it makes people feel better then by all means continue......
This best part about this discussion is that by reading this statement alone, I can't tell if or which side you'd be on. i.e. Are the people doing the kneeling overly offended, or are the people bothered by the kneeling overly offended, or is everyone overly offendable!?!
