Ish definitely says some idiotic things, and does have some idiot in him but this is out of context. He was basically trying to tell Marc that you can find scientists to back any kind of argument.
He didn’t say he agreed with this, but was using this as an extreme example to back his belief that the earth could be flat
To be fair, Marc holds a lot of pandering, nonsensical positions (such as LGBTQ discrimination being equal to or worse than anti black racism and discrimination, or that no one should be in prison). However, when it comes academia and studying, he’s on a different level.
I won’t be surprised if Ish doesn’t even engage him anymore because he’s getting embarrassed in all corners of the internet
