Knowledge is power

Have you ever heard something so ridiculous that all you can do is sputter, wishing you had words to counter it?
Sometimes, what you really need is a good course in logic.
If you can hope to counter some of the more negative and wide-spread beliefs about the GLBTQ, you can't just shout, "That's so untrue!". Well, you could. But people aren't too likely to believe you. You need proof. And proof often requires certain things.

• You may need to define certain words, like 'evil',
• You may need to set premises that everyone has to agree on, which isn't actually that hard if you start simple, and
• You need an ability to recognize what's logical and what's not.

Therefore, there are some courses that will be invaluable to you if you ever plan on speaking up. And please, do plan on speaking up someday. Maybe not today. Maybe not this year. But someday.
Basic logic and rhetoric are the most important, in my book. Look for something that promises to help you construct a good argument, and something that teaches you to recognize fallacies.
Geometry is also good, because geometry proofs are a lot like arguments, just with lines, points, and math instead of terms, fallacies, and examples, but it's a big course to take just for the proofs part of it. You'll likely take geometry anyway, or already have. If you already have, and have forgotten it, look online or borrow someone's book and quickly read through the bit on beginning proofs.
Even though you're less likely to take logic and rhetoric, you need it to be able to argue well. One of my rhetoric courses also had some fallacies in it, but I like having extra practice.
I'll give you a little more to go on about why this is so important in my next post.
