How many of you are right-handed? I myself am right-handed. As a right-handed person, the world is suited to me. I never face inconvenience due to being right-handed. I always fit in being right-handed. It is the default. It is the majority.
How often would a right-handed person notice the difficulties of being left-handed? There are plenty (add to this list if you'd like): from scissors never being suited to their hands...
...to desk positions making comfort difficult, to credit card machines being on the wrong side
Being left-handed is on that person's mind when they come across situations that distinguish lefties and righties.
I can't deny the struggles of left-handedness legitimately because I just haven't experienced them. Unless, of course, it was opposite day and all the desks were for lefties, all the scissors in the box didn't fit my hand and etc.
That's privilege, if you got it, you can't see it.
