Help me defeat/debate socialism!

It bugs me I can’t find it, but somewhere on here (it may be in one of the low content threads, but I might remember it being in a relevant topical thread) is a video that goes through various arguments and juxtaposes them with “no good or service should be provided at the barrel of a gun”. Does anyone know where this is? The title has something to do with “how to win a debate/argument in one sentence” or something like that.

Also, for the OP, this older post and this new thread might be helpful
