Overthinking tweets. It's reading the tea leaves and not actually talking to the person that is a major big time problem in our society. The liberals overreact all the time and the conservatives like to point out the hypocrisy. I am sick of this stuff and I just prefer to let people just talk face to face.
In biology's "units of selection" debate, selfish individuals have a selective advantage over altruistic ones. But units composed of altruistic individuals, whether they be sports teams or military units, out-compete teams comprised of selfish individuals. The only time I won a sports championship was the 1983 Salt Lake City Floor Hockey League Championship. That was a team that thrived on teamwork. And my old army unit: Anyone would have thrown themselves on a hand grenade to save a fellow soldier. Teamwork wins.
