Hating isn't illegal, immoral or even necessarily a bad idea. Hate can be justified. Hate is dangerous in politics as is any strong emotion. Trying to hold a country together demands compromise, which in turn requires moderation.

Facebook is empowering mass surveillance and propaganda, and encourages outrage and knee-jerk reactions. Trying to separate out who is using that power for good or ill and judge equivalence based on that is risky. If the judgment is wrong great damage will be done.

It is better to to acknowledge that power in itself is dangerous, and political power should be carefully controlled. Controlling and limiting political power has been a very successful strategy leading to excellent results in the past.
