I mean large in a relative sense. If there is a known small number of elected people, and we know that only few of them will be gay/bi, and we still find out every year or so that someone loudly campaigning against gay rights visited same-sex prostitutes or has a stash of related porn... Then either it's common or there's some weird correlation between that behaviour and drive for powerful positions.
A great explanation of this that I read somewhere was that only a gay person could believe the doomsday scenario of homosexuality ending human reproduction. A gay person thinks “huh that’s scary, what if everyone is like me” while a straight person thinks “I have 4 kids, how could that possibly happen.”
> That's also the correct use of an Oxford/serial comma, yes?
In the off chance you were being serious, no. An Oxford comma goes (or doesn't go) after the second to last (penultimate) item, not after the final. And even then it's only used when there's a conjunction between the penultimate and last item.
Formerly secret, and perhaps extrapolating (surely for N > 0 discovered cases, there are M > 0 still secret cases, since it seems unlikely to have a 100% reveal rate). And "large numbers" is highly subjective in this case. It would be reasonable to consider two to be a high number for something so surprising.
