Remember that the next time you want to complain about something going on in the public schools that you don't like. It's just the price you'll have to pay, so be ready to deal with whatever they dish out at you. You might as well join the NEA and Moveon.org
Some of us don't just hang out on message boards and complain. I've spent the last three years in school to become a teacher. I plan to teach in a low income area because the teaching I've seen go on there is abysmal. I'll NEVER join the NEA and every year I send letters to the local PTA membership drive committee head explaining EXACTLY why I'll never join them.
I see that there are problems. My own children's schools are fairly good, but with some weak spots that we supplement at home. My oldest is entering 8th grade and has not had even one class mention puberty, not to mention STD's or condoms on bananas. I monitored the information he learned about Muslims (early civilations, last year) and it was basic information. There was no propaganda.
In short, I don't stand by and complain. I am very involved with my children's teachers and very knowledgable about what they are learning and how they are learning it. I believe that public education is a worthy ideal. I am willing to stand up and do what I can to improve it.
