This not a new thing. Years ago, I drove a school bus for ‘special needs’ kids. Many of these kids can be quite affectionate. Because there are, and have been for years, so many ‘Karens’, we were told by management, that if a child hugs you, you are to raise your hands above your head, so no one can accuse you of anything untoward. With the CCP-Coronavirus, I guess it isn’t so much that the Karens fear of sexual assault against kids now, but fear of ‘rona virus. Welcome to Bizarro World!
Years ago I read of one savvy politician who, when suddenly "hugged" by an out-of-nowhere female, stretched his arms out sideways to prevent such a charge.
