Because if you start justifying these kinds of things....
Republicans have already been justifying it. It was only days ago that a Republican said [paraphrasing] "theres a revolution already going on and it will be bloodless if the left doesnt interfere".
Republicans have already been justifying the death of BIPoC, trans kids, the queer community, Palestinians and anyone who opposes their genocide.... the list goes on. And its mealy mouthed liberals that always say shit like "oh but we shouldn't start justifying using violence, even in defence" from their positions of privilege.
WTF do you think is going to happen after November, whether Trump wins or not? They have been laying out the justification for using violence for 4 fucking years and you've slept through it, hoping its just some nightmare you'll wake up from.
Democracy does not work with violence.
How do you think your form of 'democracy' was achieved? You ballot box is awash with so much fucking blood that you would piss your pants if you had a tiny inkling. And most of it is from those who your country mercilessly crushed for you to have it. You dont live in a democracy. You live in a military/prison/pharma industrial corporatist state that masquerades in a trenchcoat as a democratic Republic
The govt will ban voices that are pro-china as well as anti. The marker tends to be those who people will form behind and have the ability to create movements. It's about keeping people atomised.
