Really? Besides anonymous internet posters, who would be in the first category? I smell strawmen.
In the second category, there are some who are rabid anti-interventionists. Many of them are libertarians and would support, for example, gay marriage in the US.
At first I thought it was about a prof asserting that murderers who happened to be gay shouldn't be executed. Then I got confused when I saw it was Grove City.
That's not the only strawman. As I recall the Ugandan death penalty was not for someone having gay sex. It was for knowingly transmitting aids and gay pederasty.
