politics from a dumb ass point of view

why is it if you try to tell some one something they start speaking bullshit with the iadea that they knew what you were saying. as far as i could tell getting ten words out of an opinion should not give you the right to start arguing that persons view. one should try to lesson to new ideas sit on it weigh it for a day or two. then and only then does one have the right to start picking your opinion apart. one does not have an open mind if you can not keep your mouth shut and lesson you might even hear something new and crazy to put with your opinion. don't ask for an opinion if your only going to give them ten words or less. its just not right.
