Come on, dude. I only ruled out harassment and attempts to get people fired. If you can't think of any other ways to "challenge someone's ideas" on your own, you're beyond help from me.

I'd love for you to address the other points in my response:

Thiel is hired for his ideas. You say that he can not be fired for his ideas. This is a problem.

Here, I'll try to address it, using simple words:

There are different kinds of ideas. He was hired for his business ideas. It is not a problem that he shouldn't be fired because he has other kinds of ideas, too. People should be allowed to have different ideas. It wrong and immature to want to hurt them because they disagree with you. You are not doing good by trying to hurt them. Trying to hurt people is bad.

If you disagree, instead of hurting them, you can try to express your ideas without trying to hurt them. You could express yourself by writing a blog, by writing obtuse internet comments, by peacefully holding a sign somewhere, or by doing something creative! Just don't try to creatively hurt people, because hurting people is bad.
