Having hobbies is all well and good, I have them as well, but to not think politics has an impact on quite literally everything in your life requiring therapy is…a take.
Stating that politics have an impact on everything is just a statement of fact.
In just the examples you gave, some sort of political situation has impacted them - the price of Legos, modern interpretations of ancient history (through the lens of modern political discourse and what lead to the fall of Rome as an easy example), media regulation/censorship, the list goes on. It is possible to recognize that these things are impacted and not “think about them all the time.”
Ultimately, places like Lemmy are largely news aggregators, so you are going to get a lot of stuff related to the news (i.e. politics). It’s a bit tough to discuss the “latest in dog walking” for any period if time to largely anonymous people online when compared to “US geopolitics” or “global conflicts,” because those things are ever evolving.
“Be the change you want to see in the world” is the only real solution to that problem. News aggregation is an easy thong because its relatively universal - niche hobbies are not by definition, so its kind of up to people to make them happen.
