"The fact that you're a HackerNews user, means that you're most probably white and male. That's not racist, it's statistics."

=> Assuming someone is of certain gender and certain race, based on the environment is the most sexist and racist thing you can say. Again, you don't seem to realize how asshole of a behavior that is, but let's take some time to imagine if the OP was a black woman, and some guy on a forum says "You're most probably (I say that in the statistical sense) a white middleclass guy (I am too BTW)." hahaha I don't even know where to start.

Heres what you can do next:

1. Maybe wonder if there's something wrong with yourself when you claim to want to help these people who are affected by racism and sexism, when everyone on this thread is telling you you're the one who's being racist and sexist. Kinda ironic, right?

2. Or keep doing your thing. People call that "hipster wannabe activism". It may blow your mind but "hipster activism" is actually a thing. Read this article: http://www.yeshacallahan.com/is-hipster-activism-the-new-act... Yup that sounds pretty much like you, exactly down to the behavior of sharing all the links for awareness and trying to preach.

I know I'm being harsh, and maybe you are actually a nice guy, just misguided. People can get excitied about something they recently learned, especially if they believe it's the right thing. Hopefully you will actually try going through this thread and read what other people are telling you and giving a serious thought on if your approach is the right way.
