Donating money to her clearly isn't a waste because of all the rats coming out of the woodwork to complain that people are fighting back against cancel culture. It's revealing how many supposedly right wing figures are liberal shills.

Nigger means nothing, its a corruption of an old European language's word for black and barely resembles that word any longer. Its power is entirely self inflicted, and no child is born with a weakness into it in their genes. If this kid was damaged by it in an extra way, that is their parent/community/media literally breaking them in a specific way.
The child was in a public space committing a crime. That is an action that should be admonished in some way because children need to be raised. To use your very logic, having no one respond in opposition to what he is doing is creating the idea that what he is doing is acceptable and not opposed.
I've already given you what she said was rude, and it was a rash decision made in frustration to stop him from damaging her property. But to assign labels as large as abuse to it is nonsense, made from a place of fragility and privilege.
