when you do it, you don't consider it "fucking the poor". Dems knew this was coming, used to support the measure themselves before Trump, and this was very clearly the main issue in the last election and the voters spoke. at this point, you are unwilling to support a budget bill with even a pittance for a Wall purely to cause trump a loss. in other words, you are "fucking the poor" for your own political concerns.
You need to stop feeling so morally superior when you are actually doing what you are accusing others of doing.
