Pride and Prejudice

Today my thoughts and values were challenged by a speaker that was presenting information on prejudice and multi-culturalism. You know, I really don't have a problem with being challenged on my ideas but sometimes I get a little overly sensitive when I feel like others believe that all the bad in the world was/is created by the "white folks." I mean, I am all for growth and equality and I accept that my heritage was part of the problem. HOWEVER, that being said, I do get tired of defending actions that I did not commit. I appreciate his point of view and that it is his job to move people out of the comfort zones and question their own attitudes. I understand that the only way to change is to confront, BUT...I really found myself getting frustrated. Is this just pride on my part or do I have validity in my feelings? I think that we live in a multicultural society and we need to make changes to how we interact with others from different vantage points. That major change needs to be, in mind, mutual RESPECT for one another and variations in cultures! Am I the only person who sometimes feels a sense of guilt and then subsequently, anger when presented with these thoughts?
