I've a strong liberal political affiliation, though I don't attempt to force these beliefs on other people.
In summary, and again, like most people, I'm "looking for someone who can both laugh and be serious." However, these descriptions are problematic due to their vagueness, as it is not clear which subjects one acknowledges as warranting serious attention or about what one like's to laugh. These subtle details can only be realized through primarily face-to-face contact and conversation (i.e. dating and fraternizing).
