Admittedly it's very murky to see how it's organized and run..
They are somewhat leftist, but certainly not communist. Do you know what communist means or are you just using at as an insult?
The founder of my local maker space was an actual communist party member so yes I know what it means. He was not the only one and I have no doubt other maker spaces with close CCC ties will be similar. Somewhat leftist is the understatement of the year.
Personally I have absolutely no problem with a persons political beliefs so that is not an insult. I have a problem with fascism. If I believe something different I should not be penalized or viewed as a threat.
I am not a fan of the CCC or their organization and will continue to share my experiences of them with others.
