You are taking the statement of "toxic individualism" to mean "all individualism is toxic" rather than "certain parts of individualism can become toxic if not followed."

It is possible to say "some things could be done better" without meaning "throw it all away."

You’re equivocating, your parent specifically named an example of toxic individualism, they did not say or imply that individualism is toxic.

The term "toxic individualism" doesn't mean that individualism is inherently toxic, like "toxic masculinity" doesn't mean that about masculinity in the general case. These terms mean the over-expression of their worst aspects.

Lol, the irony of this post is succulent.

Society in itself is the act of exchanging some of ones individualism and freedom for a group identity.

Alligators don't have what we call a society, and they do things that we'd consider anti-social like eat the young of our own kind. The individual has ultimate freedom to do whatever they want. Humans consider these freedoms anti-social and harmful to others and restrict your behaviors in these manners by ever increasing punishment including death.

Effectively your statement boils down to a childs tantrum of "I want to do whatever I want to do and damn everyone else"

Saying that a type of individualism is toxic, doesn't mean that all individualism is toxic. Did adjectives change somehow?

Nobody said that that individualism is toxic

Well, feel free to drive yourself to another society once we get ours fixed.
