You seem determined to take issue with the concept of a bidet. That's OK no one is forcing you to use one. The toilet seat attachment ones are super cheap and convenient. You don't have to get up and go anywhere. You just turn a knob when you're done pooping and you get cleaner than you can with paper. Feels good to be clean.

Like back to the arm poop analogy, if you for some reason were getting shit on your arm every single day, sometimes multiple times, then having to go do the shower soap towell thing becomes a hassle. Maybe it makes sense to have a special hose next to where you keep getting shit on you to make clean up easier.

It's a single wipe on clean skin. Much less paper used. No abraison. No mess. If you got shit on your arm would you be satisfied just wiping if off with paper?

What changed is that unchecked power and increasing public presence have caused his behaviour to become increasingly erratic, exposing him for the charlatan he is.

Sorry I can't add much to your question, though I'm super interested to see other responses. What struck me is why you think it would be at all obvious to anyone else that you associate Sunday with yellow? What are your 'obvious reasons'? I'm genuinely interested.
