I seem to always get pulled in to discussions about 'politically correct' terminology. Anyway, these days the least offensive term used for non-white people seems to be 'people of color.' Most of the globe is populated with 'people of color.'
As for the ratio of xjws of color posting on the board...there is probably some statistical formula that could be applied, if someone really wanted to get picky. You would have to figure out the ratio of white persons to people of color in the jw population, and then that percentage might be applied to the xjw community that has access to the internet and this discussion forum. But, it has been said that statistics are just another name for lies. Just my 2 cents worth...
I am half Asian, half British Isle mix...I'm not Native American (First Nation to the Canadians) but could very easily play one on TV! Rocky is German and Irish. Our children our Heinz 57!
