I think you're right. The left has made lots of hay by co-opting the language, and by using certain terms and phrases they hear, and by changing the meaning or context, they can use it to their advantage.
Another important point to remember is that the MSM lives in a "sound-bite" world. They are happy to repeat almost anything that puts conservatives in a bad light, including, but not limited to bastardizing the language.
That is reason enough to pay attention to what is being done to our language.
