Users usually typically flag advocacy/rallying posts on HN, especially if they make the frontpage. It doesn't have to do with the specific cause being advocated. It's because they're off topic on HN since they don't primarily appeal to intellectual curiosity. We also tend to ban such sites, for the same reason.
This has been the case for many years, and it isn't a judgment on either the site or the cause—it's just about the scope of this forum.
