you are sorely uninformed. most teachers in the district I teach in would revolt if they found out where their money actually went. sure, some of them up north may be all for most of these groups, but you paint a broad brush with your statement. elementary teachers would especially be ashamed to find out where their money went, in my experience.
What have you done about giving your union dues to charity instead of to the union thugs? I will be glad to help you.
