You’re responding as though someone said “don’t clean yourself”. What they said was “it’s weird to call not using a bidet disturbing, given how uncommon they are”.
You’re drawing a line for where you think better hygiene is and putting everyone not on your side in the “disturbing” category, even though that’s anywhere from “about half the people” to “almost everyone” depending on region.

What I’m saying isn’t controversial at all

That you felt the need to say that is a pretty clear sign that it is.

Bidet’s do provide some hygiene benefits, but they’re not the perfect system you’re making them out to be.
If you got feces on your hands, you wouldn’t clean them by just wiping them with paper. You also wouldn’t just run water on them for a short while and then carry on.
They can irritate the anal opening and let bacteria bother the irritation. They can cause disruption to vaginal flora. The nozzle is a source of fecal contamination between people.

Yes, spraying your butt with water is usually cleaner. The actually significant cleansing comes from washing your hands with soap and water, bathing regularly, and not handling shared items with your buttocks.
