While I dont like the channel, at all, while I find Colin a pretentious asshole, him leaving will ultimately change Kinda Funny's dynamics, it became an echo-chamber. He added fair counterpoints to Greg's overly optimistic nature.
If this has anything to do with the stupid Dad Joke Colin made(it's too much of a coincidence), then it was a really, really, asshole-ish decision by Greg. Kinda Funny has been in total damage control mode, over a simple, stupid, joke. It's pathetic.
They should learn a thing or two with Yoko Taro on how to deal with non-controversies. The way he dealt with 2B's butt-versy was masterful.
