Wow! What is so wrong about one human being saying thanks to another human being?

The male and female support boards are open for all to read including the public. Now imagine a woman reads the post in the male forum and she is reading it because she is looking for support for a male friend/husband/brother. She finds the information in the male forum post very informative and is so grateful she thanks the poster by clicking a button that generates the 'thanks for this' reply. And you are upset by this??
