Our changing language...

I have been watching Cooking Channel TV since it started several years ago. It is part of the Scripps Howard family of media outlets which include the DIY, HGTV, and Food Networks. After viewing many programs, trailers, and clips it has become clear to me how much the English language is changing. We as a country are getting lazy with our usage. One individual identified as a pizza cook, talks about a "pseudo theory" in which one judges each pizza eaten with the first pizza you ate. Really? A pseudo theory? I guess the individual really does not know what a theory is suppose to do. How about this one. "I want to help share out what I know." or "Vegetables that I grew out of my garden." I know these are little things, but they are played over and over making them acceptable usage for many.  Sigh. And people wonder why our culture is changing in a negative way.
