I hope so !!! I want as many heathens around me as possible !!

No one is an island.

We are more Freethinkers, Yes. But we have congregated here. Pun intended. It's human nature to seek out those similar to ourselves.

No, we are bucking the "In God We Trust" mentality in America.

As part of the human species, one of our evolutionary imperatives is that we are inherently social animals. Because ot this humans tend to seek others that are most like themselves to fulfill requisite need. It is true with the people on this blog as well. We belong to the human species, so we're susceptible to the same drives for social contact. As humans we are also capable of abstract thought which means we are also capable of rationalizing why we need this social contact. But by the fact that we participate in this blog, we are bowing to our need for social contact. Short answer long

I believe that our ego, the 'I' is derivative of the 'We', and our context within the collective whole that nurtured us. It isn't so much cogito, sum as it cogitamus, sum.

Yup.
Just try to post anything here that is the slightest bit controversial, and you'll quickly see this.

All humans are subject to it to an extent.

How do you define the "herd mentality"?

As far as I can tell from the variety of views on display here.....NO.. . I think we are all a bunch of freethinkers and by definition we are free to think outside the box.
