It shocks me that still in our current time people have a hard time figuring out what the difference between drag queens and transgendered women is. I know from firsthand experience that some people think there is no difference between the two, and that could not be farther from the truth. Comparing the two is like comparing Saturn the planet to a Sony television; there is literally no comparison because there are completely different things.
Here are examples of Drag Queens.
RuPaul
Miss Fame
Adore Delano
Willam Belli
Here are examples of transgender women.
Laverne Cox
Candis Cayne
If you can't tell the clear difference, I'll point it out to you. The people I noted as drag queens like Miss Fame and Willam Belli etc., are men. They are not in any way female. While they do make careers of altering their appearance through makeup, padding, and clothing, they do not live their day to day lives as women. On the flip-side, people such as Carmen Carrera and Laverne Cox have always been women. Although they may have had to go through different struggles than other women to get to where they are now, they have always been and will always be women.
People tend to assume that because men dress as women whether it be just putting on high heels, etc or being a full blown drag queen, that they wish to be a woman. This is not true. Unless clearly stated by the person that the reason they are wearing a specific type of clothing is to be seen as a certain gender, it's best to assume that they're just experimenting with fashion. Although it should be noted that not all transgender women have the financial ability to make their inner self a visible reality to the rest of the world. So someone may look one gender but identify as the other. I know that it can be hard to remember how to stay politically correct in a world where some people's visuals don't match up with what we've seen for a long time, but it's important to stay compassionate and accepting.
Overall here is what you should know. Drag queens are men that use a combination of makeup, clothing, and sometimes many other things to create the illusion of the female form. This doesn't not make them actual women. On the opposite hand, transgender women are just women; nothing more, nothing less.
