How big is the group you are talking about?
This type of argument seems to be used for tone policing and "know your place" silencing.
Well we have about 40% or more of registered voters who do not vote, take out those who cannot due to being in prison, instated that do not allow released convicted felons to vote, those that are discriminated, and those that just cannot make it regardless of thereason, I'm sure we are still left with a fairly sizeable chunk of voters in the 10s of millions that just sit on their hands and do nothing, or protest by not voting. Those are the people who, often I find are the loudest complainers of shitty policies that hurt them. They are a problem.
Why is a totally different argument, but it starts with voting. Followed by contacting you representatives. At a minimum, everyone should be doing this. Not everyone needs to join their local party or run for office, but refusing to take part and let you voice be heard by your representatives helps create the issues some of the they feel no reason to vote at all.
Youd be amazed how quickly a representative will change their side on something when 80% of their district contacts them. Prior to the announcement that over half the house is in favor, mine was not one. She was flooded with calls, letters and emails by most of her constituents. She jumped on board before to help get closer to 50%. She was one that said she will follow Pelosi but jumped the gun because we made it happen.
