I think your heart’s in the right place here, but it comes across as an over-generalization to say that no one in the Linux community will try to convert you. Whether they have any valid points or will be successful in doing so is a very different matter. I’d argue that much of the FSF’s official website is dedicated to exactly this, and even they can often come across as endorsing the attitude of moral superiority that Linux users are often mocked for IMO. (I’m a Linux user, but I believe this is a serious issue in our community that we need to take seriously.)
And you not voting will help…how? By failing to vote, you become complicit in the failings of whatever fascist or gemocidal maniac you allowed into office by your inaction. You’re not stopping the war in Gaza by passing on voting - you’re just allowing these systems of injustice to continue without you by your defeatism and inaction. Shame.
