Leftists rationalize that they care more, have more empathy, sympathy, etc. Don't be fooled. They suffer from an untreated mental condition that no amount of windmills, high taxes, open borders, third-term abortions, street anarchy will ever cure
It's not a recent observation on my part; it goes back decades, so I've had a long time to figure out the meaning of this peculiar phenomenon. Specifically, it's that Conservatives like me seem to enjoy the lion's share of being in a good mood, feeling optimistic, trusting that the many forms of rugged individualism can solve most problems, smiling easily and often, and generally seeing both the present and future as glasses half full.
Not one of these things can be said of leftists, and nothing brought that truth more vividly alive than watching the Democrat and Republican conventions in August.
