Over at The Daou Report, an entry from Blogs for Bush is linked to which finds that the removal of a cross at Mount Soledad in San Diego from city property is an example of "outright war against religion in this country" and that the cross was removed "so that atheism may be preferred," with it "appear[ing] that the preference of an athiest to not have a cross trumps the right of believers to enjoy their religion without discrimination."
So we see that the enforcement of the establishment clause of the first amendment constitutes "outright war" and not allowing Christians to violate that clause constitutes religious discrimination. Mark Noonan, the author of the entry, confuses secularism for atheism. If the city of San Diego were preferencing atheism they would have replaced the cross with something like this (sorry, I now have access to a scanner, but, unfortunately, I can not draw.)
Update -Alonzo has written a post about militant atheists which complements this one nicely.
