You are trying to turn a critique into a movement. Is that possible? Sure. That's how all movements start.
But critique is easy and it is everywhere. All the cranky old men who write to the newspapers decrying every new development and change in public policy are engaging in critique. Not one of them ever started a movement.
Movements are hard. Never having started a movement myself, I'm not going to offer advice on how to do it. Besides, it would not be writing advice. But I'm pretty sure that just writing a blog of social critique and asking readers to do the work of starting a movement because you are too busy to do it yourself is not going to work.
On the other hand, there is definitely a communication component to is. Jordan Peterson, who definitely did what you are seeking to do, spawned a movement off one post on Quora. But he took advantage of that moment by writing a bestselling book, making hundreds of YouTube videos, and going on a book tour that nearly killed him.
But notice that Peterson did not do this off criticism alone. Yes, there is a lot of cultural criticism in his work, but at the core there is a program for personal improvement that has appealed to many people.
I think it is very difficult to start a movement of criticism alone. Do you have a program for self improvement or political action to go with it?
The most you are likely to get just out of a cranky blog of social criticism is a few cranky followers who happen to agree with you. And they are not going to share or promote your cranky blog unless they think that sharing your blog will make them look better in the eyes of the people in their social circle that they want to impress.
And guess what, criticism of the zeitgeist does not tend to impress most people's social circle. The zeitgeist is the zeitgeist because most people agree with it. The depth of most people's social criticism is that the guy next door got a better deal than they did.
So, is getting other people to do the work of turning your part time efforts at social criticism into a movement a reasonable ask. Probably not.
