You seem to be reading a lot into a simple business decision. Most advertisers probably don't want their brand advertised alongside (and thus associated with) highly controversial content, including racist content. Thus most ad networks have general policies against hate speech and the like. Same reason you can't monetize videos about war on youtube. It's not a conspiracy by google to stop people from making videos about war (which you are still free to do), advertisers just don't want their valuable brands becoming mentally associated with horrifying footage of human slaughter.
