Everyone has a right to speech, even those you disagree with politically.

I guess the assertion above is that they were not banned for mere speech?

I don't think it is. I think the assertion is that people who have been accused of supporting something that has been seen as a coup by supporters of the administration should have their speech banned, anyone who helps them speak should be arrested, and anyone who listens to them speak should be fined $10,000 per violation.

but not in India or Turkey apparently

There was no coup. There was a protest. The protesters wanted the military to enact a coup. And the military did not attempt a coup. You simply cannot claim that elderly people with bibles and flags amounts to a coup or even an attempt at one.

This was discussed at length only two days ago. If you disagree with this, just refer to this comment thread:

My account is rate limited to ~5 posts/hour so I don't plan on recreating that thread here.

Asking for a coup IS an attempted coup

When we, Ukrainians, stood up to oligarchiat/mafia russian-puppet governing party in 2013-2014, what do you call this?

Protests that actually turned into a coup ? That doesn't seem to have happened in Brazil. (Yet.)

Discussion about would-be coups seems to be fraught... probably best to avoid the term ?? I'm remembering those funny (for an outsider) images of the January 6th USA Capitol invaders seemingly being lost at what they were supposed to be doing once in the building... (though this took a darker turn when we learned, much later, that Trump did not show up because his own security service prevented him to !)

I don't think so. It's just a political position. Those people would rather the military ruled over them.
