Titled "Left-Speak : a glossary of terms", it's a strawman of a "liberal" in which the terms "socialist", "progressive", "leftist" and "liberal" are used interchangeably.

In it, "racist" is defined as "anyone who has decided that individuals should be judged not by the color of their skin but by the content of their character."

The quote from MLK Jr is used here ironically, to point out apparent liberal hypocrisy. The entry (rather, all the entries, of which there are 77) is a projection of what the OP believes a "liberal" would mean when they speak. This entry continues with a heavily misconstrued explanation of "intersectionality".

Considering that the US is the *only first world country* where health care isn't universally accessible ("Universal Healthcare" is defined as , Specifically, a means by which you would be obliged to support or tolerate a certain political party or doctrine in order to save your very life") and given the many references to the US constitution, Left-speak was likely written by an American conservative.
"If you parse their sentences, the speech of the Left can be at times befuddling unless you understand their unique usage of terms. So that you may better understand (liberal words) Left-speak in the future, I offer the following glossary... You might want to print this and keep it on-hand for those times when you are unable to avoid (liberal words) Left-speak. "
