This is an obvious example of someone who doesn't understand the argument he's presenting. This is the problem with having no actual knowledge and relying on the internet/youtube to have your say for you. When someone questions you, you end up showing your true level (as in above, where you went into full circular logic). You might type all the transcripts you wish from youtube, but when someone presses, you will always embarrass yourself. It's particularly hilarious because the argument you're trying to present is very well-known (not to mention basic).Ok , now you are just straw-manning it. Yes it is an assumption(Premise) that is what a deductive argument is. Truth of the conclusion provided that the argument's premises (assumptions) are true.
