Set aside politics for a minute...the things school systems do...like father - daughter dances being discriminatory, change Christmas to Holidays...etc. Think how a teacher or teachers who have different values, beliefs, traditions than your own...might cause a bit of confusion for your kids from teacher to teacher...and from elementary school, to middle school, and high school.
I think that parents need to ask themselves a simple question: "Do I want other people teaching my kids their values, their beliefs, their traditions.
In other words...
Should values, beliefs (religion, etc), and traditions that your families (mother's, dads, single mom's, single dad's...etc) have been carried forward by generations... that you feel is important...be minimized, criticized, or substituted with other values, beliefs, and traditions by someone that you don't have a personal relationship with?
If you kid comes home and says, "Mommy, daddy...my teacher said you are stupid people because you believe in the bible." "Mommy, daddy...my teacher said its okay for boys to kiss boys and girls to kiss girls and be in love." "Mommy, daddy...my teacher said you're going to a bad place when you die because you say the lord's name in vain." "Mommy, daddy...my teacher says that gay people are really bad and need to be put in jail." "Mommy, daddy...my teacher says Christmas is bad because people lied about Jesus being god's son. "Mommy, daddy...my friends at school said that sometimes it's okay for me to put candy in my pocket at the store and not pay for it. "Mommy, daddy...my friends at school say people who aren't our color is trying to take our country away from us."
Now take all of the examples above...and reverse their meanings. That could be possible from teacher to teacher, school level to school level.
By the time a kid gets through high school...their minds will be ****ed up as a chinese fire drill. Ooooops. I can't say "chinese fire drill". I mean "asian fire drill". Hmmmmmm, wait I can't say that either...that's being a bigot. No...it's okay as long as I don't say "slant eyed chinese or asian. Uh oh...noooo, nooo, I can't say that because my teacher said ....yadda, yadda,..
To me...that's like saying to your kid:
Go away kid...listen to your teachers and school friends...I don't have time for your nonsense!
Let the schools stick with educating your kids with things like..Washington chopped down a cherry tree. Washington's father asked him, "Son, did you chop down the cherry tree?" Washington replied, "Oh hell no, dad...I wouldn't do **** like that!"
