I wonder if you would have cared so much if the previous "elected" president were German national socialists? Because the previous "elected" were Muslim Brotherhood rats.
I don't like commenting on others' politics and governments (Egypt in this case). I do for my own because I have the right to. But wouldn't a predominantely Muslim country vote for a Muslim government? Wouldn't a Christian-founded country like the US ensure its president is Christian? I think it's fair and logical.
My understanding is that the people of Egypt voted for a Muslim representation. They got just that (for better or worse). Until el-Sisi, with his military power, decided it didn't suit his own views.
