I would totally agree with this statement, except we have been bucketing people that are considered "different" for years.
I understand its kinda odd to find yourself being labeled as "cis" because you consider it the normal, default. If you didn't fit into the normal and default you were already pigeonholed and labeled.
Yes, we as a society have been bucketing people forever and I'm sure you'd agree its absurd. It always seemed odd to me that the "bucketed" people try to change that view by inventing new, softer, PC labels...rather than demand that they not be labeled at all.
I do consider myself "normal" because I do fall in line with 95%+ of the population. I avoided using that word purposefully because it's essentially calling others abnormal. If someone wants to bucket me that's their prerogative. I find it more amusing than anything else...but concerning also. To me it almost feels like the non-white, -straight, -male, -etc. people saying: oh yeah, well I will bucket you now. So there!
It's small time and defeats real progress.
