Right memes read as genuinely informed about real problems, usually surrounding crime and government corruption; they tend to make you think about what you would like to see done to solve problems.

Left memes are concerned with broadly defined amorphous problems, rife with internal contradictions and offer no insights or solutions; this is because if the problems were ever solved, leftists would lose the smug self satisfaction of feeling like they're more enlightened than other people. Some part of them knows they're completely ignorant, but won't admit it to themselves or each other.
