Touching another person is a power play. Obama did it all the time as a way to show dominance over the other person. MIchelle did too. Remember when she slapped Queen Elizabeth on her back! The look on the queen’s face was priceless.
But is it sexual harassment? If my boss puts his hand on my shoulder in congratulations, should I take this as a sexual pass? That's where this is leading. And now sexual harassment can quickly turn to job loss and prison sentences. This is why MGTOW is so popular. No wonder so many men want nothing to do with women anymore.
