Yeah I don't know what Mexican-American is, I've heard of Hispanic-American / Latino-American but now I guess we are combining nationalities.

I've been to HI, you want to guess how many Mexican-Americans they have there?

If the producers of the show wanted to show "what America looks like" in HI and wanted to get rid of the White guy lead then why wouldn't have they gone with a Japanese-American or a Pacific Islander-American actor?

About height, Tom Selleck is 6'-4", the new guy is 5'-9".
