You’re only touching the tip of an iceberg here…this is by no means confined to “Republicans” (whatever that means any more). It’s everywhere.
Our so-called civilization is run by adolescent males. We have a massive deficit of humility, wisdom, integrity, and respect in our culture. More and more our public discourse resembles a grade school playground at its worst.

And, make that hiring decision by a simple majority?
