You've taken all the meaning out of the word. Founders with thick accents should also be afraid that their speaking abilities or lack thereof will lower the value of the companies that they are founding. Would that make them... "xenophobic"... about themselves?

I was actually trying to clarify the meaning of the word to take the pejorative bite out of it. A fear of strangers makes sense in some contexts.

Of course foreigners cannot be xenophobic about themselves, they aren't foreigners to themselves. Agreed that if you have a strong accent it makes sense to worry about it; this is the pressure that drives assimilation.
