NO!, the "in-group" is not recent. the liberals from the old ABUZZ are still here on A2K calling other posters, pigs, racists...etc and promoting their "in-group" agendas. An example, is their non-ending attacks on P. Rosa.
That group may have always been lurking in the background. However, in earlier years, discussion on a2k was dominated by intelligent posters from across the political spectrum.
Now discussion is dominated by that group making outrageous attacks against anyone who does not conform to their extremist ideology.
