Our friend asked to post his comment here.
He has found a shocking video, supporting his statement, which was originally set as a joke. Amigo wrote: “I strongly believe that surrounding makes me think and act accordingly.

I would end up as a Commie.”
Here is the video. “The human raised by animals”
