To be fair, that's what it shows by default. I recently created an account just for a short-term purpose, after years of not using it, and the starting algorithmic TL was just right-wing rage-bait about either my country or the US; nothing else. I chose to experiment, and it took days of active curation and follows for the algorithmic TL to stop trying and just show me game/anime stuff for example.

I can see people which open an account without a specific purpose just letting themselves fall into the first rabbit hole Twitter shows them.
