They're literally changing it, and they are doing it on purpose.

They don't want the people in their group to be able to have an honest, frank, reasonable conversation with "The Enemy".

Today, not only are both groups operating on a completely different set of definitions for common words, the far left are pushing more and more for the idea that the words themselves have no meanings, and all the meaning is in the interpretation of the person reading or hearing them.

It's ridiculous.
