Well, i would rather prefer taking in fellow Muslim Afghan, then a racist Pakistani mindlessly pandering xenophobic rants against the Afghan community for everything that occurs. A narrative similar to those espoused by the far right in the west.
First and foremost, the Egyptian government is completely incompetent and does not work for the shared interest of its populace. I'm completely against this wall, I belive the Palestinians in Gaza who face many challenges, should be allowed to freely enter Egypt.
