And here's an example of how it's done.
Public schools are buying a US history textbook which contains politically mangled revisionist language regarding the 2nd amendement, the right to keep and bear Arms.
One can buy the two-star rated chunk of junk entitled 'United States History: Preparing for the Advanced Placement Examination' on Amazon for $100 bucks in hardcover.
The textbook tries to rewrite the 2nd amendment thusly, "The people have a right to keep and bear arms in a state militia."
To refresh, the actual language reads, "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."
The US Supreme Court reviewed the 2nd amendment at least twice in 200 years. The court made a very big deal out of the phrasing, and even the placement of the commas in the original text. The key phrase "the right of the PEOPLE to keep and bear Arms" is distinct and irrefutable. One need not be a member of a militia to own guns!
If you have kids in public schools and want to protect them from such abuse, take the time to read their textbooks, especially the ones on civics. Do your part to eradicate crap like this, it's important.
