All the rational arguments against it are now buried in a downvoted and deleted thread

Exactly right. The comment by CarlShuman is valuable. To the extent that it warrants a thread.

What if anyone gets killed as a result of not reading this thread because he was never exposed to the arguments of why it would be a really bad idea to violently oppose AGI research?

Passionately suppressing the conversation could also convey a message of "Shush. Don't tell anyone." as well as showing you take the idea seriously. This is in stark contrast to signalling that you think the whole idea is just silly, because reasoning like Carl's is so damn obvious.
