I think don't there's automatically evidence on "both sides" of a issue. I don't issues actually tend to have just two sides. For a given issue or situation, there can be one, two, five or ten plausible models.

The worst thing about having roughly two very polarized ideologies constantly visible in society is that the slightly more clever people wind-up expecting that "the truth is somewhere in the middle". In a given case, there's no reason to think that.
