@failedLyndonLaRouchite changing ones views is not a thing that requires apology. under many circumstances, it's not changing them that would be discreditable.

goldberg, though, does not so much change his views as his tactics for discrediting the people he disagrees with. a few years ago he'd tar them "liberal fascists". now they are "anti-liberals on the left". they refer to his same enemies! it's a bit orwellian.
