Eminem opposing Trump does not establish that his politics are “hate driven.” Strongly opposing someone because you regard them as harmful, or telling people who promote bigotry and intolerance to fuck off, isn't inherently the same as building your politics around hatred. You're collapsing the distinction between opposing intolerance and practicing it.
That standard looks especially selective coming from you. Your own rhetoric is constantly saturated with contempt, insults, hostile assumptions, superiority, punishment, retaliation, and judgment toward people you dislike. Yet you single out Eminem's hostility toward Trump as evidence of some uniquely hateful political outlook while treating your own much more pervasive hostility as justified. The issue isn't whether Eminem can be hostile. Obviously he can. It's your unsupported leap from “he strongly dislikes Trump and MAGA” to “his politics are driven by hatred.”
Your treatment of Clinton and Trump shows the same selectivity. You repeatedly invoke Clinton's association with Epstein to reinforce your condemnation of him, while insisting there is “no evidence” against Trump despite Trump's documented relationship with Epstein, including multiple flights on Epstein's plane. Trump also publicly described entering pageant dressing rooms while contestants were changing, while former Miss Teen USA contestants separately alleged that he entered their dressing room while minors were changing.
So you can separate Eminem's musical talent from your judgment of his politics, but that doesn't make your claim about his motives established. You're applying a much harsher interpretation to hostility when it comes from someone you oppose while giving considerably more latitude to hostility that comes from you or is directed at people you dislike.
