You keep using those words, but you clearly don’t comprehend their meaning.
“Selfish” is demanding exclusive access to public thoroughfares. “Selfish” is insisting that you are the only person who can use a public road. “Selfish” is denying public access to public roads.
“Tyranny” is when an individual forces the public to bend to their personal whims, instead of allowing them to conduct their own affairs in peace.
These people are not protesting. They are infringing on the rights of every person they deliberately delay.
Protesters have the right to speak. They do not have the right to demand a captive audience to hear their speech. They do not have the right to stop anyone who wants to move. They do not have the right to harass. You can speak; you cannot force anyone to listen, and you should be jailed for trying.
