They seem to support our enemies because they do support our enemies.
The real question becomes: why do people who live well because of the success of their work allows them to have lots of toys and luxuries support systems that would tear them into shreds, line them up against a brick wall and shoot them because of their livestyle or what they believe or how they dress if they ever had to live in a society under the thumbs of the people they support?
Why do they denigrate the system that gave them their wealth and freedom to do these things?
This is the real question.
