The 1776 Outrage

Everyone knows that 1776 is a glorious date in American history since thaat is when we delared our independence from the tyranny of King George III.   However some black trolls are claiming that 1776 was a year of slavery.  What's worse is that a high school principal sided with the trolls and openly declared his hatred of America.  People like him are nothing but traitors and should be treated as such.
