So by the same token, the Whakatane Christmas parade, and no doubt others, should be banned as some roads are closed for that and it might inconvenience people.
Protests should be banned on pavements, as the pavement is being blocked and it might inconvenience someone.
Where, indeed, does it end.
Presumably you agree with the UKs slide into, I dunno, fascism, where you are prosecuted under a law where you are not allowed to explain your motives to a jury of your peers ?
And another silly strawman argument. Such a parade is known in advance and certainly not in commute time. The argument is not about inconveniencing people; it is about preventing people's rights and safety - freedom of movement.
Blocking a road without due notice and approval doesn't just inconvenience people. It takes away their rights and it creates harm.
