Well, either the Obama administration is composed of puppets of anti-gay fundamentalists (puppets who lit the White House in rainbow colors upon the SCOTUS deciding that gay marriage bans were unconstitutional), or perhaps their relationship with Saudi Arabia is motivated by reasons other than supposedly shared religious fundamentalism, and in fact religious fundamentalism has nothing to do with this.

(Incidentally, the majority of wars, adjusted by the number of victims, as well as the majority of repressive actions against citizens by their own states throughout the last century were initiated by people whom you could more accurately describe as anti-religious fundamentalists than religious fundamentalists. It could be that religious fundamentalism, bad as it is, is not necessarily the main theme in every bad event in history, but just one of the many variations on the main theme.)
