Often referred to as the "silent majority".

I think this is many (?most?) people's experience, whilst media (social/traditional) are geared towards demonizing both "sides", to increase engagement. I say "sides", because most people's opinions skew left/right depending on the issue in question, rather than fitting perfectly into the stereotypical archetypes.
