Webster's is the final authority of all terms, musical or not. Show me something they've been wrong about.
Okay... How about "The Enjoyment of Music" eighth edition, a college textbook.
Chord - "Simultaneous combination of three or more tones that constitute a single block of harmony".
Double-stop - "Playing two notes simultaneously on a string instrument".
Now you show me anywhere it says that a chord can be two notes. I don't think you can do it.
You say you've been playing a long time, well I've been playing a long time too; longer than you. Think about it... play a C and a G, what chord is that? major, minor, diminished, sus2, etc. Is it none of these, or all of these?
When you use the term "two note chord" you are spreading misinformation.
