I know what it's called.
It's still part of the march, and still arrogant and undemocratic.
Ermmmm you seem , as usual, to have things arse about tit,.....
the right to peacefully protest or march proudly behind your political preferences banner or the issues that motivate you is the very definition of democracy ........attempts to stifle, a desire to not allow your opposites a political voice or debate are the hall marks of extremism be it fascist or communist ( both political dictatorships that stifle dissent)
Lack of a clue about such fundamental political principals would call into question why you post here ..
The other option is that you are a troll
So which is it are you ignorant or a troll??
( and btw before you come back with a pejorative ad hominem insult , my political beliefs mean I'm unlikely to march on May 1st ......however I would never question the right of those to whom it means something , the right to March and display whatever banner or issue they please)
