In The Merchant of Venice, what is another reason apart from racial prejudice that Morroco greeted Portia with the following line?"Mislike me not...

I think it is very important to realise the historical
context of the time regarding issues of skin colour. We are so exposed to a variety of
different skin tones today that we hardly think of it as anything strange, and if there
is anyone who does, we label them a racist, with good reason. However, in Shakespeare's
times, only a minority of white English people would have seen a black person, and so
there was an aura of mystique and wonder about them. Many people actually believed, for
example, that if you gave a black person a good bath and scrub, they would come out
white. Therefore it is important not to jump to conclusions and label Portia as a
racist. Morocco is trying to present himself as a fellow human being to Portia, who
probably would not have travelled that much and may have been scared or nervous about
meeting someone like Morocco for the first time.
