no one in the west wipes with the hands, there are bidets, or shower hoes/pipes. using your hand would be degrading.
In the west of what? Usually the West means the USA or Western Europe.
Actually, using the hand is what God wants. After all, He GAVE you your hands for free. If you don't use them, you are dishonoring God.
wiping your ass with the hands is something for arabs that life in the desert, in europe india, and china there are everywhere plants and vegetation and also water (all cities built on rivers) you can use as emergency toilet paper.
and people can keep their hand clean,
thank God i have not been born as an arab living in the desert, must be really disgusting to life as an arab beduin.

In the wetter lands, there are all kinds of plants that people can use. Think of the corn cobs used in America before there were Sears catalogs... and before TP.
In dry lands, washing the hands with sand is way more practical than using plants, which often can't be found.
