Esperanto

It's great!  If you want to say the opposite of something, you just put "mal" before it.

theism= tiesmo
atheist= atiesmo

Wait.  What?  That's fucking stupid.  What is the point of making a prefix you don't even use?  It should either be "netiesmo" (not theist) or "maltiesmo" (strong atheist "god doesn't exist").

Neither.  My mother tongue is English, and I speak acquired but native-level French with my (wife-children-inlaws) family and some colleagues and friends.  Like most Esperanto speakers, I learned it as an adult and use it with some of my acquaintances, but not nearly as much as I use my native, home or work language(s).  It has taken me a significant amount of time and effort get to where I am in French, including marrying a native French speaker and living in a French-speaking country for several years; amazingly, with a much, *MUCH* smaller investment, I have come to speak Esperanto almost as well as I do French.

I hope you don't think that of me :-), although I believe I see where you're coming from.  FWIW, not all Esperanto speakers are creepily obsessed about it.  A friend and former colleague of mine and I have lunch once a week, speaking Esperanto, but we talk about everything but - work, life, human stupidity, anything but Esperanto.  I'm certainly not the only Esperanto speaker out there who thinks that even though it's a cool and fun language, it's not an object of worship (sly tie-back to the original topic of this thread :-).
