Outside the martial arts world: I think most people who make fun of it have taken it when they were little, and hated it because they got bored with it. Then they tell all of their friends how dumb it was and then everybody makes fun of it. Inside the martial arts world: People see Olympic TKD. When they get in close they kind of grab each other. In a real situation, you would get a knee to the groin. Plus, few street fighters use their feet. Also, because of all the TKD McDojos that are springing up around the world. Your TKD school doesn't sound at all like a McDojo, White Belt. There are good schools and bad schools. Sounds like you've picked a good one.
