The people are not the victim here, the people are the ones who are guilty this happened in the first place.
USA may be a flawed democracy, but it is still a democracy.
So no this is not victim blaming.

The marches show others they aren’t alone.

Again only excuses. You can march, but that is not enough. There needs to be clear demands, and there needs to be planned actions if demands aren't met.
It's trivial to put up websites that can work independently from the media controlled by the 1%.
That can organize local groups, and states and federal at the highest level.
But nobody is doing anything. Apparently Americans won't sacrifice anything to rescue their democracy and country. 😔

Unfortunately you average Democrat is not your best friend on this issue, they are happily letting everything happen, and some even support it! They hope they will take the next turn, and win the next election by a landslide, and then the pendulum can go on like that forever. Except this may be the last chance for USA to save their democracy.
