I brought this up during the Woodstock discussion, simply as a reason for not being interested in Woodstock.
Vietnam and the protests seem to be a very opinionated topic, despite being 40 years old.
Apparently there are still hard opinions, with little give and take. That sounds like "Politics" rather than "Coffee Shop." ;)
That said, I thought the timing of this article was interesting. It ran on the AP wire, ABC news just today.
