Its seems like latent racism at its best.
It's not really racism. At the time, back inthe 30's, most JW's were white, in a time when in social circles black and white americans didn't really fraternize, they had picked the 144000 number. After 50 years of being existence, they were getting close to that many partaking, so they had to say "from here on out you all are just regular JW's, not annointed". It had NOTHING to do with race but more to do with their numbers getting to big to match the doctrine. Fast forward when, in America, at least, fraternization between black and white americans was common, the JW's were spreading into Mexico, China, etc., and hardly any of those people can partake because the number was already sealed.
