I STILL do not see that article say washing with soil is better than washing with soap. Show me ONE article, just ONE that says using dirt to wash your hands is BETTER THAN USING SOAP. Believe you me, I've tried "soil better than soap", "dirt better than soap" and "clay better than soap", and the results are a BIG FAT ZERO.

After all, the whole purpose of samak is to clean your the germs off your hands, right?

This is called solipsism, you only see things you want to see. That article says mud harnessed to fight infectsion. First of all, you don't even know what kind of mud they are referring to or its application. Secondly... dog saliva is NOT an infection. That's using the wrong tool to do the wrong job. Why not I help u samak your hands with a sand blaster and see how sparkly clean your hands will be.
See, this is what is wrong with Islam, it's a non-progressive religion. The practitioners will rather stick to old obsolete beliefs rather than use their own brains to think logically.
