These people's worlds are defined by those boxes.
Even though they preach that you should be free to do whatever you want, if you don't fit perfectly into their boxes, you are the most evil of evil.

It is identity politics
practiced by people who were indoctrinated in a T-F, multiple choice world.
Where you are wrong, bad, outcast if you answer the questions wrong.

So, the boxes are their life.

There is already a civil war happening.
Those with boxes vs those without boxes.
