Wiping ass with toilet paper is so gross?

In countries like Turkey, India and Japan, they have water bidets attached to clean the ass which is so sanitary and clean.
But here its so dirty that people clean their asses with paper than water.
That area is the dirtiest part yet nobody bothers to clean there with water.
And lots of people don't even shower daily. Plus some girls even wipe from the back to the front.
Why don't western people also petition for shower jets and bidets for personal hygiene?

How gross is that?
