…what if I just don’t like seeing news that only makes me feel angry or bad on my feed.
That’s not the meaning of the word politics. [...] This other thing you’re talking about, bad news, that’s not what politics is. Sure, bad news is political, but that’s because everything is political.
I feel you missed a chance to get a less aggressive perspective on all of this.
The other person told you they "just come here to see tech, cars, and art.". Probably hinting at a casual experience, with little to no opinionated or controversial topics. Maybe they have a mental health too, maybe they have a super political day job, or whatever. There are many reasons for people to seek another experience on Lemmy than you do. This does not necessarily imply they are your political enemies and need a lesson from you.
The belief that bad news and politics are the same thing has been used to justify transphobia, sexism, and racism.
While in a specific way it is true that everything is politics, this does not mean it is okay to make everything about politics. You cannot connect a persons desire to have Lemmy without politics to justifications about transphobia, sexism, and racism. That's crossing several lines.
