Wishing people to death really isn't cool. How would you feel if random people on the web told you they wanted you or your family to die?
Disagrement - okay - but calling for people to be killed - not okay, especially not over over something as utterly inconsequential as ads on a damn website. Remember that you just committed a very serious criminal offense with your post. I'm not sure how this reflects on the compony you work for as per your profile.
