for me, libertarianism is a cancer. that doesnt make me a communist, and I am definitely not. but hyper-individualism is a literal poison to society.
If libertarianism and individualism are "a cancer" and "literal poison" then then they are the most benign and beneficial ones I've ever heard of. Of course any ideology has a spectrum of interpretations and people involved, but the core ideas of "don't hurt people and don't take their stuff" (and maybe also "leave me alone") seem pretty good to me.
