Queer was used to denote (pejoratively) a gay person starting in the late 19th century, and increasingly was used that way into the fifties and sixties. The term was later reclaimed by the queer community in the 80s, 90s, and aughts.

The term, particularly in the mood century, was absolutely used to describe gay people.

I didn't say that I doubted that the use of the term to refer to gay people was current when the ball game was created. I said that I doubted that that’s the sense that was referenced in the name of the ball game.

The pejorative use to refer to gay people wasn't the dominant use of the term until, well, quite late in the 20th Century, and the structure of the game makes it a whole lot less likely that the reference was a pejorative reference to a sexual minority rather than simply the odd man out.

It's kind of like if you someone argued that the “ball” in the name of association football was a reference to testicles and not the main piece of equipment in the game. Sure, the word also was used that way at the time, but it doesn't make as much sense in context as the alternative, and without some evidence beyond the mere existence of the sense of the word it's not a particularly compelling explanation.
