Underneath it all, Sheldon may be as 'queer as a three dollar bill'.
Sheldon also has some peculiarities of his behavior. Like his campaigning against allowing the reimportation of prescription medicines from Canada. It turns out Sheldon had sold out to the drug manufacturers and duped his followers into acting as unwitting lobbyists for the drug companies. The House Conservative Caucus barred Sheldon from their meetings, because of that little escapade. Sheldon is nothing better than a con man, a common grifter.
There's a lot to be said about homosexuals who victimize other homosexuals but few homosexuals are willing to admit that that occurs. When and if they do, however, inevitably it's blamed on heterosexuals' "homophobia" somehow "forcing" homosexuals to go violent upon one another. Or dishonest otherwise, as you describe.
