The Notch Brigade are like the Flat Earthers of the phone world, despite all evidence to the contrary they will only believe in the notch.
It usually gets pointed out that as the X has sold in the millions and this must be a sign of how great of a design the X is, there are millions of morons out there so it is inevitable that a lot of X's will get sold. The amount of X's sold is not an indicator of good design but rather that people will buy any old crap and think it's great.
Lets point out some other great features of the X;
Construction: Because Stainless Steel and Glass are now considered rare and premium.
OLED Screen: Because colour shift is awesome
Camera: because you misssed red eye which has been extinct in the camera world for over a decade
UI: Because you prefer multiple gestures to close apps in multi tasking
Face ID: Because you hate unlocking your device when its flat on a table.
Uniqueness: China is coming for you.
Feel free to carry on defending the X though, you will sound exactly like a Flat Earther.
