My point precisely (which I've mentioned already) is that we don't need to dumb down education any more than it's been dumbed down. I strongly believe in making philosophy more accessible and in general giving people more access to specialized fields. This would start by educating them using the language of the specialists rather than some stupid version of the language.
And right here is where you are being pretentious about your dearly beloved.

It's a common flaw whenever one is totally smitten, and it does result in some rather odd behaviour.

It's not "dumbing down" to use a word in its traditionally established sense. That is how language works: by having established meanings attached to certain combinations of sounds. If you then attempt to bring in a new and esoteric meaning, you are going to have problems when using it in conversation with most people.
Let's concentrate on "fact", since it seems to bother you so much. It has been used for ages in common speech. It is also used in law. In law, the facts of a case are not things which, in absolute terms, cannot be disproved. They are simply things which appear to be established beyond a reasonable doubt. Using the word "fact" in this sense is not dumbing things down.
The word is used in much the same sense in everyday speech. Using it that way is
not arbitrarily redefining it to suit oneself, which is what you suggested I was doing.
