I try to interpret ambiguity charitably, so usually when it irritates me the issue isn't ambiguity, but actual exclusiveness.

A sentence like "We seek out mates among attractive members of the opposite sex," for example, isn't ambiguous at all; it simply excludes some queers from its subject.

And, just to be clear: the speakers of such sentences are free to do so, and should be.

I bring it up only because army1987 seemed to be drawing potentially false inferences from silence: the reality is I am sometimes bothered by it.
