Has any ones comment changed how you view a film?

I was watching bend it like Beckham last week when my friend came round, it was in the middle of the changing room scene where the Sikh girl is saying how she could never go out with a white,Muslim etc man. My friend commented that it was acceptable racism I.e. it's not racist it's just culture.
I don't want to get into the rights and wrongs of that but want to know if anyone else has had the way they see a favourite changes by someone else's comments, If so what?
