Mullyman, do you have something to say that isn’t this anti-gov’t thing? Seems to be a constant thread in your head.


It seems, Mr. Mullyman is concerned about wasteful spending of tax dollars, as we all should be.


Mazin I’m not anti- government I’m anti not governing for the people and not wasting the taxpayers money on their pet projects.We are Trillions in debt keep giving money we don’t have to other countries who hate us and treat hem better than the people here. I ask you do you like the current government and how things are going. I respect your view even if I may not agree with them
