Why are trending posts on Mastodon mostly negatively politically oriented?

It seems anytime I try to check out Mastodon it is always some negative political view or affiliation of why X, Y & Z is bad. Is this just what most people like boosting or is it a sign of botting to push negativity over the more positive headlines?

I do understand I can switch to any Mastodon instance I want and stick to a small community, however I like keeping up with trending topics in the world. Maybe the most popular accounts in the Mastodon community likes to rise up pitchforks every minute.
