We seldom choose our names, ourselves. The name was chosen early on to pay due respect to the two main sources of inspiration: the TeX system and the Emacs editor. TeXmacs takes the good features of both, but just because I have the same name as your parents it does not mean I'm the same kind of person. A family is not a clone hierarchy. One can argue that Javascript also has the wrong name, there are reason for this, but usually this does not stop people to appreciate the good sides.
