Give buddy a break, he got the whole speech already. I also think the tone of your last sentence there is uncalled for.
How so? It's not that hard to read Frontier's post as saying that Star Trek should be full of people with his ethnic background, and that anyone else is there just to serve some political/philosophical point about diversity. That may not be what he meant, but he hasn't posted any follow-ups to the responses to his post, so who knows?
Look, I don't know who Frontier is...maybe he/she's one of those who posts about too many gay people or Titan's crew being too diverse...if he/she does that then I withdraw my defense.
Until then it just seems like some people were being too harsh and trying to beat others with their knwoledge on common surnames around the world.
It's not about knowing trivia like what the most common name on Earth is. It's about a fundamental mindset -- Frontier implicitly argued that there's something more "normal" about Anglo-Saxon names, but there isn't. Calling Anglo-Saxon names more "normal" or "common" privileges Anglo-Saxon culture above other cultures; it implies that Anglo-Saxon culture is somehow the "default" culture for Humans, the "standard" from which other cultures deviate. But Anglo-Saxon culture is not more "normal" or "standard" and other cultures do not "deviate" from Anglo-Saxon culture; it's just another culture, no more or less valid than any other, and its names are no more normal than any other's.
Frontier may not have in any way intended to be, but when he said that there was something more "common" or "simple" about Anglo-Saxon names, he was being profoundly ethnocentric, and it's not at all hard to see where someone from another culture might be deeply insulted by the implication that his/her name isn't "common" or "simple," is somehow less normal.
