If it is a racist movement, so what?
In a legal technicality sense, racist movements of all colors should be protected under the law the same way Gay or LGBT movements are. The hypocrisy here is astounding.
If Communists want to rally, so what?
If Nazis want to rally, so what?
If Black Nationalists want to rally, so what?
If Gays want to rally, so what?
They should all be afforded the same rights. The LGBT movements around the world are just as extreme in their demands as other movements if not more so. It's wrong and I believe that in the future all manner of groups will have equal rights, something movements such as the LGBT and others will find galling in the end.
If your comment was aimed at PEGIDA, there have been no records of mass violence. There may be fringe elements and fringe violence but PEGIDA rallies in Germany have mostly if not all been peaceful. There were scuffles at today's march in Newcastle but there were British National Front and other fringe groups also present - as well as anti groups labeling PEGIDA as racist / scum / islamophobics etc.
A government minister has now, controversially, met Pegida supporters to discuss their concerns. But those supporters, not to mention the leadership, have wildly divergent opinions.
Some believe there's no place for "foreigners" in Germany. Some are right-wing extremists. Others just want a public debate about immigration.
And, without strong and consistent leadership, it is that lack of cohesion that, critics predict, will prove fatal for this movement. Link.
It's like showing some KKK members who support some random grid iron team and being cute about saying all that team's support are KKK members.
