I'm afraid I find it difficult to get past the "same-sex marriage" part. Unfortunately, the parties which are against same-sex marriage are against a lot of things that I'm for, as well, such as priority for the environment and social justice, and/or are for things that I'm against, such as kowtowing to Big Business.

Why can't there be a moderate party that espouses the policies that I want?

Living in a blue-ribbon Liberal seat, the only difference I can make is with the senate. I'm still going to put all the loony right-wing parties last, because that would be worse than loony left-wing parties getting seats.
