Most all my Latin friends and family members like their meat charred and destroyed while most of my White and Asian friends and family members like their's no more cooked than medium.
It's mostly a cultural thing if you look at the big picture.
I like them med rare and I tell whomever (usually family members) like their meat well done to take their portions and cook them further in the microwave for a few minutes.
If I'm dealing with a large group in my home I will cater to their requests.
