Henderson, they're right. It's within the country's rights to accept or refuse entry for whatever individual they wish.
Sometimes it can suck but this time around I think it wasn't a bad idea for both Kenya and the author.
Son, you have NO IDEA how hard tough it is to be a Muslim or to be from a Muslim country during the screening process of either getting in or out of the US. I get caught in security ALL the damn time because I have a flag (most likely has to do with being raised in Indonesia for a few years which is a Muslim country) and I see what those guys have to deal with. And yes I am asked, "Are you Muslim?"
