Your intent seems quite clear there. You purposely slow down to get the tailgater irritated, then once they finally decide to undertake, you gleefully (and spitefully) speed up to prevent them from getting in front of you. This is called blocking, and it's dangerous and pointless. If, as you claim, you're already keeping a safe distance from the car in front of you in the fast lane, you're now assuredly closing into an unsafe distance. So there is a contradiction in what you've been posting, and I think you're toning down your opinion because you've been rightly called on it.
