This does not match my personal experience; having lived in countries on both sides of the equation, with those in the more non-native country (South Korea) having a much less tolerant for non-American/British accents (e.g. Chinese, Indian, Filipino) than those from native or very high-fluency countries. I.e. Ive found tolerance for non-native accents to be inversely correlated with personal fluency.
