An analogy that might offend

I'm surprised I've never run across this analogy for homosexuality that now occurs to me.  Imagine a group of people who are, what we could call, alternative eaters.

For whatever reason, these folks prefer to consume food either through their nostrils or their anuses.

And imagine that sensitive individuals didn't want to exclude any of variety of preference. It's not fair that the anus eaters get all the attention, so we develop an inclusive acronym. We call anus eaters A's, and those who prefer nostril eating N's. If they enjoy both methods, we'll call them AN's.

Some like both mouth eating and anus eating, so we call them MA's. Those who like mouth eating and nostril eating, we'll call MN's. A few enjoy all three methods, so we call them Tri's or T. Those who are trying to figure out which methods they prefer, we will call I's for investigating. For all others, we'll indicate a plus sign. That leaves us with the acronym of ANANMAMNTI+.

And don't get me started on the people who like alternative excretion.
