The perennial question for the offended parents- WHY ARE YOUR CHILDREN STILL IN GOVERNMENT SCHOOL?!?!?!?!?
The answer to abusive government is to confront it, not run away in the vain hope that others solve the problem.
Local school boards are elected. Get in their faces via the PTA. Expose their radical goals. Tell others, write letters to the editor of local media. Better yet, run for a local school board seat on a platform in opposition to teaching anal intercourse to second graders.
