When contrary opinion or values are demonized, who can blame those being polled when they dodge the demonization by telling pollsters politically acceptable lies?
When contrary opinion or values are terrorized by the #BlackLivesMatter/Antifa mob, who can blame those being polled to answer dishonestly, to avoid being terrorized?
Behind the demonizing and the terrorizing is the FakeNews media that, by failing to hold such activities accountable, encourages the behavior which causes inaccurate polling.
