Yo Mann, if you have nothing to hide...hide nothing!
Hide the decline.
It was the correct decision by my standards. I’m no fan of Mann and his hockey stick. But black out the word “conservative group” and “environmentalist” and use something like “Atheist group” and “Professor of Theology” or “PETA” and “Nutritional Researcher” and even “CAIR” and “Nuclear Physics Researcher”, and see if you feel the same way.
