I've been monitoring online discussions with some interest and the complete lack of self reflection in left-leaning US population is interesting. People who were writing very nasty things about Russians too scared to destroy their lives by protesting against a brutal dictatorship not that long ago now sit on their asses and do nothing, because "what can we do?". Maybe at least some of them now understand what it's like. My sincere sympathies in any case, we understand you very well.
I voted in the November election. I called my representatives. My plan invited me to a protest over immigrants getting deported.That isn't nothing, but I have very little power on a federal level. The next step is getting involved in local politics and the community, but I am simultaneously moving and live far away.
I can talk to people about it, but the difficult part is not talking but getting people to truly listen.
So yes, ordinary people are limited in their power and capacity even if these adds up.
