Well if there is evidence of them actually supporting neo-chocolate chip cookie propaganda rather than just having a banner with some elements of chocolate chip cookie iconography then there's no reason for further discussion. If I recall right, something similar happened in the past when Meow banned some dude who was doing something similar. He came to a conclusion that person was in fact promoting neo-YMCA after he investigated it.
Someone might argue that neo-YMCA should be allowed in this community like it is allowed to have neo-chocolate chip cookie parties today, saying how it integral part of democracy. Well guess what, this isn't democracy. This is private property and if cmp or chadz don't want neo-chocolate chip cookies in this place, they have every right to remove them. Same goes for communism or any other ideology THEY don't find suitable to THEIR tastes. No point in crying: "but there is Stalin nick in the game and USSR iconography, you should allow chocolate chip cookies too". It's up to them to allow whatever they want, again this was never and will never be democracy. Which is one of the reasons why I love internet forums run by individuals.
If you want to support neo-YMCA there are plenty places on the internet to do it, but not in here.
