Why should they? are we white people going to have a sit down and think about what we as a community can do about the white extremist hate that led to one of them killing Jo Cox?
Actually the historian Tom Holland was interviewed by the BBC yesterday and made a very convincing case that actually the white European community had 'sat down' and thought about what it as a community could do. Although not in relation to Jo Cox, but in relation to the holocaust and empire. He argued that Europeans had completely reassessed their cultural underpinnings and dropped dominant ideas about racial and cultural superiority, nationalism, tribalism, etc, etc, etc.
The jist of his argument was very much that Islam as a whole still has dominant schools of thought which are othering, divide the world into us and them, good and bad, right and wrong and views Islam as a superior set of values and those outside of less worth and more deserving of hatred purely on the basis of their race or beliefs. And that this set of values is what is at it's most extreme producing extremist terrorists. It sounds very much like European attitudes in the 1930s.
He argued that Islam needs to have a process of assessing it's cultural underpinnings just like Europeans did post war and rejecting those that discriminate or push hatred.
I think he makes a very good point. Someone who doesn't want their children to marry white people or wants them to go to a segregated school and 'mix' or chooses not to interact with white neighbours or stereotypes white people as drunken fornicators might not be letting off bombs, but they're building a societal pattern of behaviour which produces some people who can't relate to those around them of a different race or with different beliefs as equal humans just as deserving of life and respect as people like them.
