Have known and worked with these people all my life. And when you explain to them why they are wrong calmly and logically, and after they look it up on Google and realize they are wrong, they will hate you forever. There is no worse insult to a functioning educated moron than to spotlight their idiocy. They will never forgive you. They live in their little fantasy bubble-world and they are happy and comfortable there. You must not rock their boat.
@240B Yup! Been there,and experienced that with people I thought were close relatives. Afterwards,it was like I had never been born. They wouldn't even nod at a "Hello".
So,of course,I went out of my way to welcome them with joy,anywhere and everywhere I saw them after that.
Fun is where you find it.
