I think many people of 1970 would never have believed being
anti-war would be a negative attribute in the future.

It was more than anti-war. Kerry was against representative government,
and thought that a vocal minority should have more power than the silent
majority of the republic. He was anti-government. His view of government,
like all communists, is that a Central Planning Authority should distribute
the revenue to the communes (Party organs), rather than capitalists
determining what was viable based on the market. It's the classic serfdom
versus freedom struggle (communists versus capitalists).

Kerry's voting record is pure communism. He is a communist.
