When you adopt leftist language you gradually adopt leftist patterns of thought. It is not a trivial matter and is not unrelated to thought and its exchange. You have succumbed to the leftist view of the world and society even as you protest it.
Interested analogy. Do you believe that the left is attempting to control our language?
Even if I made a grammar error, or unintentionally wrote “himselves”, I find it hard to imagine myself accepting the leftist agenda. Does a single individual matter, to the socialist/communist, I am probably a lost cause? Is it a victory to them, that I simply use such language? It is a victory because for the entire community to use such language, it might help them recruit someone younger and more impressionable.
I think I see what saying. I do not believe I am in any danger of adopting leftist behavior. However, I will be mindful.
