Not at all
It was a first amendment issue. Just like the ACLU defending the Klans right to march in Skokie
That was in the 60s. They have not done many similar things lately. Which seems to suggest Kessler is a Lefty plant if the ACLU is backing him. They are in on the scheme.
To be more precise it was 1978 that the KKK marched in Skokie
The Rutherford Institute also was involved in this most recent case. They are hardly a lefty group
The law suit was pure first amendment constitutional....the rest of what went on was a classic anarchist clown car
