Why do so many American Senior Citizens I run into online, hate bidets / Washlets?
They're not really senior citizens; they're employees of the Scott Paper Company and they've been shitting you.
Nobody really hates the bidets. People just don't like you, harping on about something that the rest of us couldn't care less about, but you are obviously obsessed with.
Let me be the first to tell you this. You have not heard from many senior citizens. There is only one 34 year old cranky guy (I mean no offense, andrewcranky) with multiple aliases. He tells you that he hates bidets because they don't fit his head well. He had wanted to be Green Bidet in his younger years, but couldn't physically qualify.
