You may want to stop and think about why the same morph could have different names. Yes, some of the names are all about egos and such. But consider this: You import a morph or a dinker and find it's genetic. Okay, cool, you have your very own morph and you get to name it, so you do. After several more years of breeding, you come to realize that your "new" morph is actually just a different line of an existing morph. Well, now what? You've been selling your morph under your own name. Do you just suddenly start calling your morph by the existing name? You can do that, most certainly, but people are going to be very confused. Sometimes it's good to know what "line" a morph is from. Axanthics are good examples of this. There are four lines of Axanthic (VPI, NERD, TSK, Joliff), but only two are compatible with each other, so it's good to know what line of Axanthic one has. You mentioned there are some compatible Ghosts and some that aren't; ergo, it would be a bad idea to just start calling all of the ones that look the same Ghosts.
Besides, just because it looks the same doesn't mean it actually is. Again, Axanthics are a good example of this. Butters and Lessers may be the same morph...or they may not be. Yes, they both produce BELs, but so do other morphs that look nothing like Lessers or Butters (take a look at Mojaves and Mochas...and Phantoms, since Phantom x Lesser = BELs too). The only way we could know for certain whether they are truly the same morph or not would be to sequence their genome. What if we start calling them all Lessers (or Butters), and come to find out, down the road, they each react differently with a certain morph. Now what? Now we all have to prove out our Lessers/Butters to see which one we have!
Yes, some people are full of themselves. Yes, there can be several different names for the same thing. Some people use different names for the same combo...but I can't think of one off the top of my head that has more than two different (commonly-used) names, and two isn't exactly hard to keep track of (and if it is...then use Google; it's your friend). Don't like it? Well, I don't know what to tell ya.

I will tell you, though, that whining about it will do nothing to change it. It's okay for the naming schemes people use to confuse and/or irritate you; it does many people. But your post does come across as sounding like a whiny n00b, which is why some people responded the way they did.
