You're just trying to have a nice meal with family and friends. Some nitwit decides that's a fine time to lecture people.
Sometimes I wish my kids weren’t conservative and we could get into these kinds of arguments so I could set them straight.
Alas, I did a good job as a parent and kept them on the right path. None of our kids went to big liberal PC football colleges either.
Small specialized engineering university for one, two are completing bachelors online, fourth went into trades work.
