Louis P. Sheldon (1934–2020)

It's useful if you want to read the homophobic talking points, and see just how bad their evidence is. The authors cites long debunked studies, doesn't seem to understand anything about biology, is appallingly ignorant about history, and makes a lot of claims that are patently false--it even cites Paul Cameron as an authority!

It shows how insular that world is.

There are some funny aspects to it, largely because the author is so clueless.
