Welcome to Hacker News. Such submissions are mostly not on-topic according to the HN guidelines linked at the bottom of the page but there are persistent activist users who try to drag off-topic social issues onto Hacker News when the opportunity presents itself under the thin pretext that "everything is political". Most such submissions don't have the momentum to reach the HN front page but occasionally one does.

The joke's on them; it likely erodes support for their causes.
