It's not off topic. Here, let me show you. You said factors other than race play a role in success. I asked you what those factors were. The first factor that you listed was luck. Remember, you listed this ahead of hard work, which tells me that it came to your mind before hard work did. I asked for an example luck playing a factor. You gave me an example. I showed you that it was a poor example. You asked to change the subject and said that it was off topic. Hence, it is in fact not off topic.
