None of my business what people want to do with their lives. Should be their choice and I find it absolutely baffling how the main opposition to this comes from the (often religious) libertarians who otherwise can't stop banging on about freedoms and the "nanny state" whilst simultaneously doing everything they can to tell others how to and how not to live their lives.
I get that there's an exploitation angle in some cases but it really annoys me how religious people insist that everyone lives by the same values as them. If you think that humans don't have the right to preside over life and death because God gave you life then fine, nobody's forcing you to take up the option of an early but comfortable passage to the next place, so please don't stop everyone else who doesn't believe in that from having the option themselves.
Same with gay marriage, abortion, etc. It's the 21st century.
