The reason that I despise Elton John is that he was the headliner at an event, some number of years back, the purpose of which was to raise money to lobby for lowering the age of consent. I think it is a safe bet to assume that the perverts will keep working at this until there is no legal age limit for consent.
I suspect you're misconstruing the efforts of a few years ago to bring England's homosexual age of consent, then 18, in line with that of heterosexuals, then 16. It question of equality under law. As reflected in this story, it's now 16 for age of consent regardless of the partner's sexes.
A quick look suggests you state of Maryland appears to have an age of consent of 16 with no apparently separate restriction on homosexuals.
