Stupid accusation: “you make yourself right all the time”

My sister, bless her heart, recently leveled this idiotic accusation against me: “No one can argue with you, cuz you can make anything favor you”.

You’ve basically just said you’re stupid. No one can make ME think they are right on any subject they talk about, I don’t know why you would be any different. -Of course anyone can argue anything, but not everyone can be right. If you really think that I spin things so I’m right about everything when I’m actually dead wrong or just misleading – then pinpoint it. Call me on it. expose me for being a total dip for brains and claim the victory that is rightfully yours…

If you can’t, then you’re either wrong, or too dumb to articulate why you are right. Neither of those is my problem.
