Good on him for standing up
Congratulations on how the guy is dealing with the issue : openly, honestly and calmly.
It is high time the rabid prudes step down a notch and let other people live their lives. Purple is not the colour of prostitution either - it seems to me that it is seen every Easter in Christian churches and catholic cardinals have been seen wearing that color - so zip it, prudes, you're just revealing your shameful desires as usual.
