For I too found the whistles brutally irritating when I, and others, were trying to have intelligent conversations with like-minded marchers and hand out the complimentary Morning Stars.
I was sorely tempted to abandon my generally peaceful intentions, when whistle-blowers seemed to deliberately stifle meaningful conversation - they were no better than the worst capitalist gutter rags.
Bands and chants, Yes. Cacophony, No.
