If you only criticize civilian casualties when Palestine resists, then your concern isn't civilian casualties. Your concern is Palestine resisting massacre.
I doubt there's any. There's not a good definition of a "political meme" that wouldn't have many people disagreeing whether certain memes are political or not, hence breeding power trip mods and bias. Most likely, it'll just be allowing the political memes that agree with mods opinions, or are status quo to the mods, and hence not seemingly "political" even if it is.
But if you find one, please comment it here. I'd love to see it.
