I know that most white people find it beyond offensive when people call into question the presumed acceptability and presumed superiority of their culture, which they prefer to judge by its ideals and not its reality.  Believe it or not, I understand completely.  The emotional, psychological and identity pain I went through when I finally understood how violent and destructive western barbarity is took decades to resolve and reconcile for myself.   

However, I disagree that recognizing the destruction of the culture everywhere it has gone in the world, including its land of origin - Europe - divides anything worth holding together.  The only thing it divides is European-based culture from its false self-image as the height of human intelligence, decency and development.  For the gazillionth time, this is not about the 'past.'  It is about the culture itself, then and now.  Europe has been the most violent, vicious place on Earth for nearly 2000 years.  They just don't tell you that.
