I myself did not downvote you, however I think I know why others did. This is the kind of thing that would have gotten better reception in the open thread. This is just to short for a discussion article, as you are not really saying anything yourself in this post.
If you post this there, you could get a whole conversation going about the topic. It's fine, all you did wrong was you didn't understand fully the community norms, so I will upvote you to slightly balance out these downvotes. And for the future, you now know our norms, so that you know where to publish.
I disagree - a post where we all post our hypothetical apostasies would be totally appropriate - if it was appropriate to post them anywhere, which it is not.
By learning to overcome the Nirvana fallacy, I have managed to find my hypothetical apostasy: I want to cure aging!
I think that awesome stuff will happen in the far future and I plan on getting there, so I'll do my best to make sure that I stay alive as long as I can. (Also, my primitive survival instincts make me want to become immortal.) Unfortunately, due to my evolutionary baggage, my own genes are going to kill me in a few decades.
What's your hypothetical apostasy and how do you plan to put it in practice?
Edit #1: If you're downvoting this article, I'd like to know why you're doing that. Send me a message or reply here.
Edit #2: I totally misunderstood what the hypothetical apostasy means. I was under the impression that it meant defending a view that most people deem too weird to contemplate. See Lark's explanation. I guess you should downvote this article!
