Well, I pick my friends very carefully....
The 'tribe' of skeptics sit in their 'right' place because they've earned
it, not because they read it, or had it told to them, or because they
live amongst those who do, and because every fact is backed up by the
entire universe, not just recited on a Sunday from a pew.
However, it is a 'xenophobia' of ideas and capacity to use them, not a
xenophobia of a racial or an ideological characteristic. But, yes, if one
does not doubt, question, or strive to find the facts, one is not welcome
beyond a visit.
