1. I do not think languages that are under-used have less value than languages that are used more. If this man values Klingon, he ought to be able to teach his kid the language.
2. Using your own assumptions, you can make similar arguments for teaching "lesser" languages like Spanish or Chinese in an English speaking environment. I think that is a dangerous and scary proposition.
3. Most children are able to pick up the english language outside of the household (ie. every single 2nd generation immigrant from a non-english speaking country).
What I really find amusing is that this incident is from 10 years ago, but the original link breathlessly reports it like breaking news.
Wired, August 1999: http://www.wired.com/wired/archive/7.08/mustread.html?pg=8
Language is a critical part of human development right from the beginning. Depriving a child of this, and by extension of a normal parent-child connection, in the name of some arbitrary curiosity strikes me as perverse.
This can be compared to someone teaching their child their own religion. No one should be able to restrict that because religion (and most human belief, pending that it doesn't hurt others or themselves) ought to be outside the bounds of morality.
The "Klingon community" has no system of helping its members to make friends or find mates, no useful information about the real world, no "payload" of beneficial values to inculcate in its members (as PG put it in "Lies we tell kids"), no inspirational works of art produced by people it recognises as intellectual forebears, etc. That makes it objectively inferior to pretty much any "involuntary" (religious/ethnic/geographical) community no matter how small, and even most "voluntary" communities (e.g. hackers).
Klingon is a constructed language, but it is sufficiently complex to be generative enough for actual use. Constructed languages aren't evil or irrelevant either -- look at Esparanto, which has a substantial amount of native or fluent speakers (more so than some "real" dialects).
Sapir-Whorf (heh, Worf) notwithstanding, we know that the "choice" of native language does not affect the child's cognitive capabilities negatively in any way (basically, as all languages are generative, you can express everything in any language -- if you lack the words, you make them up).
It's unusual, but it's hardly something to get your panties in a bunch over. There's no difference between speaking to your child in Klingon or any other minority language, constructed or natural. That's the beauty of it. The human mind is quite adaptive when it comes to utilizing language.
Klingon is a human language! Who does he think created Klingon. And he has a Phd? Nice logic.
