I completely understand you don't want this type of article on HN. But, you don't need to worry the site will only be articles on social justice if hackers find the topic "inherently interesting." Most people here are inherently interested in a variety of topics and that's why the community makes room for a few these "off-topic" stories.
Broken window theory. The rate of civil rights outrages worldwide is more than high enough to overwhelm the forum, so the number of completely off topic stories only remains low thanks to people visibly objecting to them.
