Never really seen this talked about, but a youtuber and geologist called potholer54 made a response to one of Crowders video, in return Crowder wanted to debate him but ran away at every chance.
The last part of the video is about the debate which never happened
another video by potholer54 on crowder, has more info about Crowder lying about the debate and blaming Crowder for it not happening
Sorry for where the video is from but not going to look at facebook to find the posts, but here is Crowder lying about having his show canceled
Maybe worth adding a part about him before his youtube success
Found an old video from 2010 of him and Amy Schumer debating
Him voicing Brain in Arthur as a child
