Yeah, you're not harming anyone else... except your children that are going to be cancer-ridden and have all sorts of mental disabilities (not that most people will notice in Australia).
You know, it's no wonder that England was such an urbane, civilized, educated, literary culture for a couple of centuries - they sent all their fundies to America and all their congenital criminals to Australia.
Anyways, when you look like those two you can't go turning down relations just because it's coming from a relation. (Clever fucking word play fuckers! WIN++)
