‘The allegation doesn’t withstand scrutiny, simply because dangerous, anti-government rhetoric is not part of today’s liberal dialogue.’

Have to disagree with this. ALF and ELF are probably considered ‘liberal’. The fact is that there are wacko extremists on all sides. It wouldn’t be hard to point to the signs displayed by a number of ‘liberals’ and anti-war protests and the like that are comparable.

Trying to say that all the extremists on one side or the other is dishonest and lessens the credibility of the article over all by trying to claim so.
