I did specify contracting, rather than spreading. I like to think that people have a right to do whatever they like with/to their own body, so long as it doesn't prevent others from doing the same. Besides, we live in a world where resources are becoming increasingly scarce. Having a few less people burning up said resources isn't a bad thing, especially when they're the cause of their own death. It's like smoking tobacco in my eyes. Very stupid, but who the fuck am I (or you) to say that something that doesn't harm a third party is immoral?
As for otherkin, I don't get it at all. Truth be told, I can't wrap my head around transgender folk either. I'm absolutely fine with both though. There are a lot of people who are very different to me, and that's pretty awesome IMO.
Live and let live, or die. Whatever. So long as it's all above board and consensual, I see no reason to judge.
I what they want to do effects only them I am cool with it.
If they want to smoke/get HIV on purpose I am not, because it costs the government a lot of money and screws everyone else up assuming they live anywhere where their is any degree of socialized medicine or governmental care for the elderly (eg. America, most of Europe and the other first world nations).
Actually apparently smoking
saves society money by killing off people faster even though they spend a lot of money combating the effect of it.
I suppose that means that smoking is totally fine then (excluding the fact that it smells terrible and is annoying).
