Because fixating on politics is bad for one's own mental health, and toxic for the community. It turns everything into a flame war about politics and divides, rather than unites, people. It suffocates interesting and worthwhile discussions. And on top of that, it doesn't even accomplish anything good to make those downsides worth it.

It never ceases to amaze me that some people can dismiss ideologies that advocate for personal threats of violence against a particular group of people as "politics".
Has it occurred to you that half the country is explicitly targeting certain demographics for a reduction in rights and services? What is "politics" for you directly affects the daily lives of many other people. When you attempt to dismiss the issue as mere politics, the people whose health and well-being is in question regard that as a personal attack. When someone brings up "politics" you might have a better conversation if you can make the empathic shift to understand why they might be prioritizing that aspect of the topic.
