I'll refer you to moviebob's commentary because he's how I learned about this and says most of what I would want to say (about the campaign, not Ms Paquin's proclivities). Here's the spot:
To draw on a couple important and applicable platitudes:
1. All that's needed for evil to triumph is for good people to do nothing.
2. If you do not speak out against an action, you are considered to have committed it yourself.
3. Justice, justice you shall pursue!
And, in a nod to the season:
4. I too was a stranger in a strange land.
This is a good consciousness alteration. I myself am guilty of "not giving a damn" about someone's sex life. I still feel to some extent that it's none of my business, nor do I want it to be, primarily for reasons of privacy. Regardless, the point is that it's not enough to ignore people and call that "tolerance". It's not enough to accept others as long as you don't have to see or think about them. I care about your sex life; I care that it is happy and healthy and fulfilling for you. I care about your identity, your ethnicity, your cultural heritage, your religion, your politics, your....well, your "you".
I give a damn about you.
