Well, I've just had a look and there's now no Rolf Harris masks listed by UK sellers on ebay but 75 Cards Against Humanity listings. As a comparison of "lowness", here's an article (albeit a few months old) on Cards Against Humanity from the same source (Daily Mail):

PMSL, text book Q+A, you didn't reverse the argument, you completely changed what it was about.

Surely the argument being one form of evil cannot be minimised by another form of evil, even if 1000 fold more prevalent: an entirely valid argument I agree. 

Anybody who can find any humour in anything related to any sort of abuse of children has a problem.

Likewise John Cleese goose steeping around and making a fool of himself in front of German guests at Fawlty Towers - does not imply that one is a nazi.  

More important though, is what I don't do, I don't just shrug my shoulders and say never mind, there's worse things to get upset about.

Nor do I.   But nor will I be dutifully PC and express mock outrage at a stupid mask costing two quid.  

I'm  glad we can agree on ethical shopping and investments.

Personally I don't get why people waste any of their time to actually give a damn!
