I'm always bemused when people claim to be beyond this "weird obsession" with skin colour, and then make it clear that their assumptions about me are based purely on my skin colour. The fact that I'm brown doesn't mean I judge you for being pinkish-white. And no, as you can see, I'm not ignoring you because of the colour of your skin. I barely even glance at people's profile pictures before responding to them.
Anyway, I appreciate the compliment as regards my writing. But if you actually read my writing, you'd see I'm making the exact opposite point to the one you seem to think I'm making...
