Being a leftist is to first think of the world, then of your country, then of your relatives, then of yourself. Being a rightist is the reverse.I don't like either/or philosophical propositions, and I especially hate false dichotomies (think, for example, of "nature vs. nurture").
There may very well be people who "think of the world first." Perhaps more observably, there are people who think of themselves first.
I respectfully suggest that both types are assholes who probably don't have many friends (for what should be fairly obvious reasons). Facebook "friends" and Twitter "followers" don't count.
