The only way would be if they have a rare genetic disorder XXY...and even then, at age 6, they don’t know this stuff unless they have been taught it. These parents are crazy - and doubtful any of their kids in these cases are XXY and have normal chromosome pairs of XY and XX - clearly male and female respectively. Thinking otherwise is a mental illness that should be treated, not encouraged and codified - there is nothing humane about distorting reality further to further confuse someone suffering a mental illness. These kids probably just started seeing people of the opposite sex wearing certain kinds of clothes, playing with certain toys, etc. and thought it looked fun and wanted to do it themselves...rather than being taught the difference between boys and girls, the behavior was encouraged...that’s messed up - people like this don’t understand the role of parents. No telling what else these kids will get into they won’t discourage or correct.
Amazingly, these people will claim that homosexuals are “born that way” and they need to be accepted for how they were born...yet they don’t believe if you are born male or female that’s reality and you can just “self identify” as the opposite and it isn’t a matter of what you were born as?
Again, “progressivism” is just stupidity. Period.
Some people think George Washington had it.
Tall, infertile, small genitals, but definitely male.
The more X's you get, looks female, but once there's a "Y" the child looks male.
