I don't think that's the takeaway at all.

There's a supply problem for women in STEM and our response has been to investigate every potential cause while investing in scholarships and outreach. If we found out that 33% of STEM employers were unwilling to hire women, we'd say, "Aha, that explains the supply problem. Let's fix that." I can't fathom spending tens of thousands of dollars to enter a highly competitve field where a third of employers will rule you out outright (and presumably more will discount you against other candidates).

Even if conservatives aren't interested for other reasons, the presence of a supply problem does not rule out bias. There is evidence of substantial self-reported bias, so there's probably bias.
