I don’t think I’ve missed the point. I did not read the post as being somehow in contrast to what you do in usual political contexts (like voting). I don’t really see what in the post suggests that.
I don’t disagree that there are other things that you can do as well. Again, I wasn’t criticising the post, just adding something. Another version of my comment could be “Yk another way you can contribute to your community? Voting.”
