It's not bigotry, but lack of investment in conversational English is frequently accompanied with lack of investment in vocabulary and idiomatic English expressions.

If you work at a large Silicon Valley company, there's always that one meeting where someone at the table, while obviously smart, speaks such an incomprehensible version of English, that whenever suggestions from their end are vocalized, everyone looks at one another with silent "did you get that?", nods politely and then moves on.
