The Border Wall might be concept I want to just go away the most.  It’s an entirely pointless, useless construct that will do almost nothing to curb undocumented immigration, because as anyone with a cursory understanding of the subject will tell you, the VAST majority of people here illegally didn’t cross the border in the dead of night, they came over perfectly legally and didn’t leave when they were supposed to.  If built, it’s a symbol of our dedication to Security Theater, or providing the visual appearance of impressive security, but lacking any real teeth to do the job.  Of course the big selling point Trump originally had was that Mexico would in fact be paying for this massively expensive project.  Mexico in laughed in Trump’s face, and now keeps trying to weasel the US and it’s citizens into paying for it.  Now he wants the military to pay for it.  Not only that, but he thinks having the Military build the damn thing falls well within the purview of national defense.  I think any normal person would feel that nagging sensation of embarrassment and shame creeping over them.  I have to give it to Trump that he seems unable to feel shame for anything.
