this is an interesting question, isnt it?
for me, voting left wing is the practical manifestation of an abstract notion of maorality. one in which i beleive in the intrinsic goodness of people, of community, and in a notion of the greater good. which in practical terms means treating people well, and with compassion and a degree (at least) of self efacement to make ones community (however local, or not, that might be) a better place, for example.
for me, right wing is born of a beleif of the rights of the individual, or ones immediate family, are more important than the wider community to the extent that one would serves ones desires at the expense of others.
based on this kind of moral distinction, such affiliations feel terribly important. i dont want to bring up my child in a world where the latter beleif system dominates.
what is interesting is that i have, therefore, always assumed that my friends have the same moral beleifs. and i have discovered recently that some dont. in fact, some have behaved appalingly to some people working for them, treated them like staff, and it really made me think hard about their world veiw and my assumptions.
anyway
