Brandon Cropper has recently gotten attention as an active Objectivist YouTuber. I don't think he's an Objectivist. I've typed in what he said to Rucka Rucka Ali about biological determinism. FYI the Objectivist view is, in short, the blank slate view.
There may be minor transcription errors and I left out some filler words and false starts. Starting at 5:40, Cropper says:
If there is at least a little bit of wiggle room there to say that genes have something to do with it, or are innate something, we can't say innate knowledge, we're not allowed to, somebody will come spank our hand. But as Objectivists we have these certain things we have to not say like "innate knowledge". But what is it? It's an innate tendency for men as opposed to women to be more aggressive? Or is it just in the nature of males as such that physical violence is part of their domain and therefore they have the predisposition for it or something? However we say it, there it is, 97% of murderers are men. How are we going to say it though?
The idea that males are innately or genetically predisposed to violence is incompatible with Ayn Rand's philosophy which clearly and directly states otherwise, and argues its case.
But what stands out to me more is that he's intentionally trying to avoid saying what he thinks. He thinks Objectivism is wrong about this, but he still wants to be an Objectivist anyway – I guess he likes other parts of Objectivism. OK but he believes the way to remain an Objectivist (or at least to avoid complaints from the YouTube audience he's pandering to like Gail Wynand pandered?) is by obeying speech restrictions – just never say anything that Objectivism disapproves of. That is totally contrary to the Objectivist spirit of free thought, inquiry and judgment. Objectivism has never tried to silence people who disagree with it. It's disturbing for a person trying to teach and lead Objectivism to view it like a religion that prohibits profanity rather than as a rational philosophy.
