Simply put: yes. As long as they are PAYING for the local public schools and have school age children, they should be allowed to utilize any part of it they so choose. Period. If you were talking about private school, you would have a point. In this case, you're 100% wrong (though your straw-man and red herring arguments and insults are so hysterical that one usually has to saunter over to DU or Huffing-glue Post to see).
So.. they LIKE parts of public schools? Odd.. we never hear about it.
My point remains.. if you rail against and eschew a school.. you have no business being on their team.
