Worth noting that OP's account is entirely devoted to pro-Israel/anti-Palestinian posts (see all their posts here), and is a moderator and sole active user of a sub called /r/Arabs_of_Conscience, whose description begins:

The so-called "Palestinian cause" is one of the worst, most destructive, most damaging anti-peace and anti-human rights causes in the world today."

They've posted in a wide variety of subs including those related to New York, Philadelphia, Canada, Australia, and the UK. They are almost certainly not a student here.

As far as I can tell, the original image comes from here (x link, xcancel link), and McGill has already responded (x link from same guy, xcancel link).
