I don't know how such things are considered in India either (and would also be interested to hear from someone). The salient point is that you do value fewer syllables in a comedy context. All it takes for someone to feel that it might be racist is to recognise that fewer syllables in comedy names may not be universal across cultures, and that taking an action that elevated one person and not another may have inadvertently selected someone of one race because of that preference.

It's not an absolute claim being made here. It's just a consideration that what we intuitively feel may not be an expression of a universally held value.
