They’ll also be exposed to other external views that are a bit more unsavory. For every kid that watches a video by an LGBT creator and learns being gay is okay, there’s another kid who watches some alpha douche Andrew Tate type that teach them women are objects. The internet is the definition of a mixed bag and should not be used to educate children
Which is why we shouldn’t be relying on social media for this stuff anyway, this should be done by schools. If a child is in an oppressive abusive house they probably won’t get social media anyway, but they will more likely have to go to school. Also teachers and counselors are professionals who know how to educate children and handle abusive situations way better then some stranger online.
