Yes, And this time their point is not being bolstered by many families seeing a family member come home in a box.
The Left was able to get some traction by becoming the self-declared voice for all Americans who were skeptical of or had grown tired of the Vietnam War. Many if not most of the people who wanted out were not radical or even liberals by today's standards.
The problem is, the Left's strategy has always been to graft its entire agenda on as riders as soon as any one issue gets any political traction. Their "logic" was that if you didn't want your son to come home in a body bag from Vietnam, you had to embrace the rest of their agenda as well - Black Panthers, Malcolm X, Mao and Che Guevera shirts and posters, the Sexual Revolution, etc.
