@maxishere keep in mind that a whole lot of people came to this platform as a rebellious act against established websites and to express protest against particular public figures.
So yep, there is a whole lot of people on here chomping at the bit to be negative particularly with regard to us politics.
The best advice is to filter out the relevant hashtags so they're just not shown to you, so hopefully you'll see more of the positive stuff you might be looking for.
