Unfortunately, everything is political, and this has always been true, and will never not be, as long as humans exist. If you were able to ignore politics, it just means you were unaware of them, likely because they weren't hurting you or anyone you cared about. The uptick in "toxic" posts in the last decade is because more people are in danger now, and are highly aware of it, and more people are actively dangerous, and are stirring the pot. It didn't get more political, it got more dangerous.
