(Most) people will live up to, or down to, the generally accepted standards set for them.
If it is someone's personal policy to accept people how they are with no qualifications, they effectively have no standards or expectations. Do you not have any measures of acceptable behavior for the people you surround yourself with? If a person is willing to tolerate absolutely anything, their opinion is literally of no consequence, and they render themselves an ineffectual. Ineffectuals are currently being railroaded. "Give an inch, they take a mile".
I would agree that people should be free to make any decision for themselves that does not adversely affect others. But I need not condone or endorse it nor should I be censored for speaking against it. Granting an advantage to someone on the basis of gender identity adversely effects those who aren't obsessed with this latest trend. And one would have to be blind to not see the physical harm being done to young people, and the indescribable harm that is to come to them should society as whole continue accept anyone "as they are".
