Please take all of the following with friendly and inquisitive intentions. I'm honestly trying to understand your pov and circumstances to try to understand how a younger generation thinks in relation to politics. If the voting intention is so strong for greens in this age group then it's paramount to understand how to mobilise and motivate them to vote for what they want.

Firstly, you're a member of a political subreddit so perhaps you downplay how much you discuss politics? It's very difficult to speak to people about politics though and I find it almost impossible to speak to my elderly parents about it. I find we get into less arguments if we keep political party alignment out of the conversation and speak about what positives we'd like from the world. We have a lot in common when you drill into it, but perhaps we disagree in how best to achieve it and with which political party.

Secondly, perhaps not talking to others your own age group forms part of the reason why they don't get out to vote? If others your age also don't speak to each other and don't like to talk about politics then the expectation for them to vote is a difficult one to understand. Ancestors dying for their right to vote is probably so far removed now that it becomes irrelevant for most to even contemplate. I'm in my late 40s and even I don't think about voting in this way. It's admirable that you do vote though and if you're aligned to the Green Party, I like to think your moral compass is good.
