The difference is that unlike BlueyLuc, Blukenzie and Sparity (or other Spike ships in general), Kataang and Dipcifica were given a free pass because all four characters in the ships were over the age of 10, if they were 9 and under like Bluey or Spike, people would have problems with it, which is what people are having with me shipping Spike with somepony or shipping Bluey with Jean-Luc bc they're children and children are unable pridto loves. (Let alone be shipped with in terms of fictional children) according to terminally online peeps.
