I suggest you read nearly every student handbook across this nation, both K-12 and University.
You must learn to educate yourself sir - you espouse views based upon your own version of reality combined with an unwillingness to corroborate those views with actual fact...
There are those judgements again. Very constructive, Sir.
I'm sorry, I already graduated from K-12 and read the student handbooks that I received when I was there. Although I read voraciously, I have no intention of traveling across country to read every student handbook. But perhaps you could help me. In what chapters does it say: "Don't criticize liberalism or you'll be accused of hate speech. Remember, the Liberals are right!"
Do you espouse your views based upon someone else's version of reality? What opinions do you hold which are based on fact? Define fact.
Look up anti-harassment laws and legislation that have found their way into state law and the aforementioned student handbooks. Or the abuses of zero tolerance, etc.
Such laws are state controlled thought police disguised as "protecting us from ourselves".
You stated you already graduated from K-12.
What then of secondary educational experience?
