Oh.....the writer doesn't mean "gay" like "happy" but "gay" like......oh.
Then the answer is definitely yes -- Lincoln was a homosexual. Along with Ruth and Naomi, David and Jonathan, Jesus and "disciple whom he loved," and St. Paul, that whole "thorn in the flesh" thing. And, lest I forget -- the Three Stooges. As my wife pointed out while we were watching them tonight, they always slept together. Even in the episodes in which they were married (to women, that is) the boys always slept together. Hmmm....that can mean only one thing, right?
The problem with this "historian" and others like him is that they have one-track minds. And diseased ones, too. They cannot even imagine strong friendships, even love, between men without those men winding up in the sack. And they cannot imagine people sharing a bed together without there being sex involved, even though that was very common not so long ago, and it was even common for travelers to share beds with strangers if there were no other accomodations in a town. Now, I'm sure that this guy has wound up in bed with strangers countless times, but....
It's pathetic that this kind of intellectual (and it's a stretch to use that word) wanking ever sees a printed page.
IMHO, you are on to something here. Simply put, these people do not know anything about love. They equate biological urges with love and thus are lost to explain anything more. Sick puppies, all.
In one of the Stooges' shorts there's a Curly line where he says, "If at first you don't succeed, keep on sucking 'till you do suck seed!"
