The problem here is one of semantics!
Yes they would be Sexist / Racist ....... but not necessarily in the negative way the words are being used now!
I must state for the record that I am both racist and sexist, in the literal sense, but NOT in the way those words are twisted into in todays society.
I view a person (initialy) by his(her) .... [I was nearly sexixt there].... obvious nationality. this is not a negative thing but an apreciation of difference. If I were to come accros a heavily tatooed Maori I would be interested in them from the point of view of their Maori(ness) (one of the few races to prevail against the imperial might of the English Navy..... but I digress). Upon speaking to them this would be superimposed with my knowledge of them as a person. It would work the same way with almost everyone I meet ..... If I were to break down and see a person wearing a hat and a particular hair style I would assume that they were Jewish and NOT ask for assistance if it were the sabbath! This would be out of respect for their perceived religon on my part! On occasion I will hold a door open for a lady whereas I may not have done so for a man. That IS sexist, but I think it is good manners an d not an affront to the fairer sex (oops there I go again being sexist )
In the same manner I expect to be judged initialy on my apperance by strangers and will fully expect them to be surprised when there innitial view of me as a great hulking fat skinheaded slob (yes I am exagerating here) is replaced by there awareness of me as a caring sensative gentle ....fat hulking skinhead!
To coin a Shatnerism "It's racism Jim ... but not as we know it"
