Sadly, that isn’t even enough.
There is a kind of ‘common sense’ that ‘doing something’ is enough, which goes hand in hand with this attitude.
As anyone will tell you, it is way easier to get people to go to a random protest, just as an example, than get people to actually organize any kind of political action, not to even mention take a politically isolated party seriously, and then start a struggle in that party, which people will likely take deeply personally.
If the people in your organization actually take revolutionary politics seriously (which they likely won’t, because the stakes seem low in an irrelevant local organization) this shouldn’t even be an issue. That ends up being a question of developing a proletarian consciousness and party discipline.
There is no ready-made solution here.
I post about revolutionary politics on a capitalist platform that serves petty-bourgeois content creators. That is also unserious in many ways, but only actual struggle to build the necessary organizational discipline will ever change the form of politics that are possible and thinkable.
That is difficult, but we have no choice. Unless you consider fascism a choice.
