rhetorical devices

i dont really watch alot of tv but i do go on youtube at least once a day and i was watching a natural hair video and it was really a debate on natural vs hair that has chemicals in it. in this video the first rhetorical device that stood out the most to me was the use of appeal to nature the female in the video was really for all natural products she argued that natural products where better for your hair simply because it was all natural and the other one that was used was black or white pretty much talking down on each others points and saying that the was no middle ground it was either you where natural or not  and one of the last ones that i could see with out truley look for it was appeals to emotion of course the females going on in this debate hair was of the content they argued and was from personal stories andwas to the point making not really valid argueements that could be back up with facts but only what they have gone through. i feel like you would find the most rhetorical devices in dabates cause people would say alot for you to be on their side
