Doesn't it annoy you when people say 'everyone is biual'?

When people state 'everyone is ,' I'm not exactly annoyed by their words however, but I enjoy telling people their statement is flat-out untrue. While often, but not limited to, a heteroual stating such a thing, when I ask him or her if she is attracted to the same in any fashion, I snicker to myself as he or she denies any same attraction, comically contradicting his or her own dubious ertion.
