Honestly, in your example, you sound like, as you put it, a dumb cunt. The purpose of "whataboutism" is to point out hypocrisy in your debate opponent's position. Your dad pointed out that a politician on your side did something equally deplorable to the one you'd called out on his side. Rather than respond to that and have a reasonable conversation about the nuance and differences between your chosen politicians, perhaps coming to better understand each other, you chose to devolve to nonsense, intentionally killing the conversation.

That screams poorly educated (but possibly with an expensive education that makes you feel superior enough that you don't bother to question yourself and your ideals).

Time stops for everything that isn't you, including air. You leave a vacuum everywhere you go and can never stay anywhere for long.
