Yes, religious wars have been around and there are similarities at this time for certain; however, it's the white supremacist attitude that I believe to be dangerous.  I also believe those that are to some degree uncomfortable with being near those that are different from themselves and it is expressed by posters sometimes here....it's somewhat of an undercurrent but is especially obvious on any article regarding First Nations people.

I'm not making a negative judgement of Canada or the US for that matter; but I believe we have something serious to deal with regarding the alt-right and it isn't just about religion.  The alt-right needs to be challenged and it's happening as all the marches show.  There will be a greater effort made in the future to protect the basically healthy societies that we have from those that hate.
