If politics is so important as to preclude romantic love where it otherwise might have blossomed, happiness will fall as a result.

Interesting. I would indeed have trouble having a close relationship with someone who is very strongly right-wing, at least today's rabid version of such a person. I don't remember things being quite so violently polarized 20, 30, or 40 years ago. We definitely disagreed about things, but not with the intensity we do today.
