Is there any reason to laugh at Indians who wash their stools by hand?

In fact, using paper after defecation is not necessarily cleaner than using hands. Because whether the paper is clean or not depends on the quality and quantity of toilet paper and the dryness of feces itself. According to the report of a medical institution, after using toilet paper, bacteria such as Escherichia coli are still detected on hands-therefore, using toilet paper cannot guarantee that hands are 100% clean. What's more, some people don't have the habit of washing their hands after defecation. In other words, there is no water to wash your hands, regardless of this habit. Therefore, it seems that it is not so much that the habits of Indians after washing their stools are unsanitary and advanced, but that other people who use toilet paper may be more unsanitary and backward. At least people specialize in making hands and have prepared water for cleaning. Do you have such a good habit? Isn't this pot calling the kettle black? In a word, if we want to completely solve the sanitary problem after defecation, we still have to rely on economic development and technological progress.
