In my opinion, I don't like to play the whole "you're selfish!" "no, you're selfish!" game. If we're being honest with ourselves, we are all selfish. We wouldn't be very good living beings if we weren't on some level. And selfishness is not necessarily the instant "bad" label a lot of people think it is. But both sides of the issue of the Right to Die are guilty of some level of selfishness one way or another.
Think about it. Pro-lifers wish to selfishly keep us trapped here the best they can, always moving to restrict access to the latest method in vogue, leaving only the classic, more brutal and difficult-to-pull-off methods available. We, on the other hand, selfishly want to act in our own self-interest and personal well-being by CTBing, ignoring the wishes of others around us and the greater whole of "society". Each side is only concerned with what they feel is the right way to go about things.
This is all to say, I agree. They are selfish. In my opinion, they should let people decide what happens to their own lives and stay the hell out of our business. But I see the issue with Pro-lifers as more of an issue of collectivism, where the overall well-being of the group is prioritized over the individuals that make it up; "the whole is greater than the sum of its parts" and all that. If individuals drop off the Earth voluntarily, then that's less tax revenue, less consumption of products and services, less productivity, etc. There is, of course, much more to the issue with Pro-lifers, but I don't exactly feel like writing a whole book about it here since it's getting late for me. TAW here on SS and ExistentialGoof on Reddit/Twitter have written extensively about them, and I feel their arguments against them hold much more value and weight than a mere slap of a "selfish" label. I don't think doing the "selfish" blame game will take us anywhere meaningful, since both parties can be reasonably found guilty of it if you pick at both sides' motivations. And even if one side is found guilty of being more selfish over the other, which tbh I'd say the Pro-lifers would be in this hypothetical ruling, what then?
Idk, just something to think about I guess.
