Being a functional adult includes trying to make rational decisions about what is good and what is bad amongst all the the noise and some bad actors. Not flailing out wildly against things that you happen not to like.
Describing me as in a death cult is rude and wrong and definitely not adult behaviour. Never mind that you don't know much about me personally.
