Exactly.
People seem unwilling or unable to see things beyond their own point of view and accept that other people may have a different opinion and it may not agree with theirs.
Many people equate "support our troops" with "support the war" (not least, the people promoting it) and yet I suspect they would be most unhappy if people put anti-war symbols up.
Utimately, like war itself, it will escalate until it gets completely out of control and just create work. I guess the people who refuse to see this don't mind being selfish ... as long as they get their way, screw everyone else and their opinions or polite requests.
