I seem to recall that actually the social networks create the opposite - a feeling that outliers are more normal than they are - for example that if you're a pedophile, you are alone until the internet where you suddenly have a community telling you that you are the normal one. It's not just your shame to hide anymore, you've got a support group telling you you're right. I don't remember where I read about that, it was years ago, but it seems more logical than targeted ads having a significant effect. Now, regulated communities where karma allows you to hide opinions you disagree with so nobody can see the debate, that's a problem. It's one of the reasons people were so surprised this election.
