Such messages tend to be of the form 'vote X! Y is crap!'. Or outright lies (qv. certain leaders) That's not even a simplified messages, the first is pure tribalistic emotive, the second, well, it misrepresent reality (aka 'wrong' or 'deceitful' or 'lie').
If the were factually based and told both sides I guess I'd be OK with it.

No, facebook is just a tool. How that tool is used is what makes it right or wrong.
