Yeah, but to be honest we don't really know what Taylor said, and she is not really the most forthright or self aware person. Honestly it could have been, and knowing Taylor was probably something like " Some kids at school were jerks today." And that's it, never mentioned again.
We know that canon Danny was probably clinically depressed, and that he had anger issues which he dealt poorly with which made him a pretty hands off permissive parent. Add to that that Taylor likes to hide things and try to avoid issues, well it is a recipe for disaster.
Now I am sure that the Protectorate did not tell Danny " hey if she gets out of line we will chuck her in juvie". They showed him the stats for unaffiliated teen capes, they promised support, they said they would try to keep her safe
Taylor has shown Danny that she can not be trusted not to sneak out, she will actively lie to him to do so. He cannot keep her safe, the Protectorate may be able to do so.
And we don't know that she wasn't direct. "Emma stole my homework and threw it away and Sophia hit me" is also a possibility. Consider that in the original story at least Taylor was a chatterbox before the bullying started and was considered gifted enough that her parents talked about her skipping grades. (Her mother thought it would be good for her, her father disagreed.) So why shouldn't we consider the possibility that she did try, try really hard to bring the bullying up with her father but that he was too caught up in his own grief, depression and other issues to pay attention to her. And due to him basically ignoring her problems over a period of time she learned not to bring them to him.
