I am not the the grandparent, but with your permission, may I ask you …

Do you agree that “pie-hole” is deprecatory?

Do you agree that the question “who cares what X says?” is likely dismissive rhetoric, rather than a genuine expression of interest in who the people are who pay attention to X?

Perhaps I've become desensitized, but "toxic" is not a synonym for "not supportive". Being dismissive of something or someone, or not agreeing with someone for that matter, does not mean a community or person is toxic. It just means you don't agree or support someone or something, and instead you have different opinions and support different positions.
