Donald Trump want's to build a wall to stop undesirables from Mexico and other shithole countries from illegally entering the United States, not to mention that it would have a devastating impact on the landscaping industry. But tall grass and unkept lawns are a price that Americans should be willing to pay to have a nation that only consist of Americans and black people. But dear Mr. Trump I think your plans to build a wall is just a minimal solution to our problem. I propose the D.O.M.E , Deny Other Mutherfuckers Entry. Plain an simple a giant impregnable dome over the entire continental US. We kick out all non Americans send them to Canada, they got a lot of unused space occupied by useless Moose. We could let black people stay, well some of them. The dome would be our answer to the nagging nuisance of diversity. We could exclude Florida, Alaska and Hawaii from the dome they're like shithole countries any way, I like 47 States better, it rolls off the tongue. Actually we could use the illegal aliens that are here already to build the dome, then kick them out after they are finished. No one leaves the dome and no one enters. Forget about a wall, that's what ladders are for. A dome is the Answer
