I don't care how many people misuse the word, or how the media portrays it. Just because the term seems to be moving toward implying transition, doesn't make it correct. Someone who is transitioning is indeed transgender, but I will not use the word to solely describe someone transitioning. I would use the word transitioning!

If you don't like how people are using the word, correct them. What the hell is the point of defining words and their usage if people can just make up their own definitions?
