You use the cleaning function first, then the dry function. Don't just dry the shit on there (well, maybe you would, but everyone else washes first, that's the point of a bidet).
Yes I'm sure the multiple countries that use them don't have a fixation on being clean or anything at all, and are very pleased with blasting shit particles around. ^^/s
"I'm sure all these people sacrificing goats to the gods haven't seen their prayers answered all the time and are wrong - can't you see how successful the Greeks and the Romans are, you idiot? /s" << you are this kind of person.
"Multiple countries" that "have a fixation" - therefore it can't be - hahahaha!
Are you against scientific evidence?
I gave multiple sources, you gave arguments from incredulity, popularity, and your personal perception of reputation of whole countries - collectively.
I use a bidet daily and sometimes theres still some poopy left after a few long sprays, I use toilet paper to dry off and do a check and then if its clean Im good to go, otherwise I hit it with some more sprays and check again. a few sheets of toilet paper is a lot better than no bidet but Im still not convinced a bidet by itself is good enough. at least here in the states bidets are simple bolt on squirters not a separate thing that might do a better job
I challenge you to get poop on your finger, wash it off under the shower head, and then rub your eyeball directly with that finger. Your towel has poop residue on it.
Sorry you have to hear it this way, but a butt towel requiring a wash in detergent and even more water than you just flushed is less eco-friendly than two squares of toilet paper.
