Wow to accept that anytime someone says UFO they actually mean alien spacecraft is ridiculous. Do you think that military testing, misinformation, hallucinations, psychological projections and t.v entertainment do not exist?
No, you misunderstand my point. My point is simply that in modern day slang and often in discussion forums (outside of military/aviation documents) UFO means "I think I saw an alien spaceship or something equally unexplainable, here's why there isn't a good explanation." In UFO related threads someone will inevitably post a non-reply that is 'argument by acronym' where a person makes a claim as to why they think the UFO they saw is unexplainable (however unlikely that may be) and the 'counter-argument' is a reading of the definition of UFO. This proves nothing and reveals just how much the replying person looks down upon the person making the claim, as if they were too stupid to understand the definition and history of the acronym and as if knowing that changes what they saw.
I will say that I agree that it gets cumbersome when people make the old joke "I saw a UFO. I mean I saw an Unidentified Flying Object because I say an Object that was Flying that I could identify." Probably for a younger crowd that sort of response is appropriate because maybe they are unfamiliar with this. But if you are old hat to this UFO poppycock business, it's more interesting to get down to the meat and potatoes of how ridiculous the ET visitation stuff is and bypass the acronym discussion. :)
