It seems that Second Thought (and their second channel, First Thought) has been silently removed from Nebula, with no comment from them or anyone on Nebula’s side.
There’s some context in the comments of a couple of reddit threads about this, that have been deleted on the Nebula subreddit:

He was talking about the genocide going on in Gaza right now, and said that there were no Israeli civilians, because they’re colonizers. Here is a link to the bit of the podcast. Really braindead, bloodthirsty, and (I don’t use this lightly, because Israel loves using the term to push their propaganda) bordering on antisemitic take. Especially when Hamas themselves are saying to the press that “any civilian causalities are unintentional”.
Stacked with his really bad takes on the Ukraine war, and it gets me thinking nobody should be listening to the guy.
