1st: it forces honest democrats to fight back, engaging in a battle chosen by Cummings. This is bad, but not baiting is even worse! It already is a tactical cost we can't avoid paying.
Either they feel completely in control of the "[whoever] against the people" narrative.
Or they are forced to.
The opposition is forced to react, otherwise it would lose the support of its core base. But by reacting, it can be seen as *over-reacting* by the majority of voters who don't pay enough attention.
So #ParliamentShutDown is deployed, because it has a veneer of deniability.
Group1: those who fight back against this government of wannabe fascists. When campaigning, they will know not to spend a single penny on anyone in this group.
Why the #ParliamentShutDown is fundamentally undemocratic needs to be explained and repeated as much as possible.
Some civil disobedience might grab the right attention, but it's a thin line: just a touch too much will backfire.
