As noted in their other reply, it is actually not a typo. A central part of their point is in that first sentence they note the extra eyes on marginalized people making more money than other marginalized people, but it’s blown out to being extremely exaggerated.

So yes, I think there is a “grave epistemic problem” with the first sentence that hurts the argument and its credibility as a whole, without having to get into the details of the argument itself.

That you called the first replier “stupid” or even their argument “stupid” is wholly unjustified.
