I am not sure why the publisher of the journal is relevant unless you're going to claim the paper is an outright lie.

It's evidence. Are you advising to ignore it? Argument from authority is fallacious but reversed stupidity is not intelligence.

Oh, I see. Thanks for the pointer.

The paper is from 1991 and seems to be about something that happened between 1988 and Gottfredson receiving a full professorship from U. Delaware in 1990? I'm not clear on the story there. But so far I'm not seeing silencing — just controversy and a question of whether the governors of an institution would choose to associate with a particular wealthy donor.

But again, I'll admit I'm coming from a libertarian background — I see a big difference between what I'd call silencing (e.g. violence or threats of violence to get someone to stop speaking their views) and withdrawing association (e.g. choosing not to cooperate with someone on account of their views). The former is really scarily common, especially in online discourse today, so I'm kinda sensitive on that. :( That's all complicated again by it being a government university involved, but except in really politicized cases that usually doesn't affect the way the institution operates internally all that much.
