Pledge...Unconstitutional?

Today US District Judge Lawrence Karlton ruled that the saying of the Pledge of Allegiance is unconstitutional, arguing that it violates a child's right to be "free from a coercive requirement to affirm God." I find it weird that this judge who claims to uphold the values of the constitution, must have never read the writings of any of the framers of the constitution, he probably hasn't even read the constitution. The 1st Amendment actually says, "Congress shall make no law respecting an establishment of religion or prohibiting the free exercise thereof..." Nowhere in the constitution does it use the phrase "separation of church and State", but wacko-leftist judges insist upon this phrase which has been used to create rulings including this one. Below I list other wacko-extreme rulings that have happened.
Stone v. Graham-1980: (I include quotes from the rulings) "It is unconstitutional (there's that good old phrase again) for students to see the Ten Commandments since they might read, meditate upon, respect or obey them."
Warsaw v. Tehachapi-1990: "It is unconstitutional for a public cemetery to have a planter in the shape of a cross...if someone were to view that cross, it could cause 'emotional distress' and thus constitute on 'injury in fact.'
Florey v. Sioux Falls School District-1979: (this is my favorite) "It is unconstitutional for a kindergarten class to ask whose birthday is celebrated by Christmas."
Every judge in America today should remember these words from the Late Chief Justice of the Supreme Court William Rehnquist: "The 'wall of separation between church and State' is a metaphor based on bad history, a metaphor which has proved useless as a guide to judging. It should be frankly and explicitly abandoned."
