With the exception of some local positions, all politicians are at best complicit in, but more likely supportive of, an unjust system. Voting matters, in the sense that you should do it when you can, but at best it only results in incremental, surface-level change, whereas what we need is a deeper change of the systems in place
Society will try and make you think of politics and governments as something “real” and fundamental, which you just have to accept and try to change in the couple approved ways they give you. But all it is is a group of people wielding the power to inflict violence on others and compelling us to fund that power. Think outside of the current systems and try to imagine a society that works for everyone rather than a small minority. Imagine a better world and then help build it
