The "outside influence" is passed on to "True Believers" who in turn press "The Faith" into social groups. Some people proselytize that more than others. My Dad wants you to know about Jesus and hey what do you think of the Conspiracy against Our President Trump and doesn't it bother you that LGbalfabet is teaching our kids in Public Schools and getting them all caught up in this perversion stuff?
The "outside influence" is only limited by people in small groups willing to actively challenge nonsense in such small groups as it rears its head. Of course, I'm willing, but this does tend to have me excluded from small social groups. Fortunately, I don't care for small group socializing. I have little in common with most people or small group socializing bullshit, and I find social jockeying tiresome.
Extremists... heh...
