I don't think its a high horse to follow the golden rule - treat others how you want to be treated. I can imagine that someone behaving in a way that is stereotypical or shows an ignorance of my own culture (whether that be Irish heritage, American, New Englander, Mets fan, etc.) would not be pleasing to me, therefore seeing people behave in a way that is stereotypical of Mexicans and ignorant of Martinez's Dominican heritage is also not pleasing to me.
