What I found to be a remarkable example was a documentary by Louis Theroux where he interviews a Ku Klux Klan leader, who is best buddies with his African-American neighbor, drinking beers on the porch together.
When Louis asked "Shouldn't you two not be sworn enemies, given your ideology?". They looked a bit surprised at each other and replied "We? We are neighbors".
