Why are daughters so special to fathers? What about sons?

Oh goodness!
At what level on the Spectrum did you test?

This puts everything you've said so far in a different light.
It complicates the issues you're dealing with, and it means each problem needs to be dealt with in a slightly different way.

Every Dad is different in the way he loves his kids.
Whether a son or a daughter is more special varies from one culture to another, and one father to another.

It's great that your father loves you and is protective. All kids need some degree of protection (relative to their age, abilities and situation.)
With autism, you do indeed need more protection and help than other kids.
If you are high functioning you will eventually be able to learn enough social skills to get by very well.

Do you ever what a drama series on TV called [i]"The Good Doctor"[/i]?
It shows the difficulties that a very high functioning doctor (with Aspergers) must cope with in a hospital setting. Usually, he succeeds.
There are many other films and novels about such people. Taken together, they show the difficulties and some of the ways to successfully cope.

But each person is unique. Ideally, it would be excellent if you could have weekly counselling with a specialist. You could think of it as akin to having a coach for maths - just someone who can help guide you in very specific ways in learning how to relate more skillfully with others.
One of your difficulties will be in reading the way others express their feelings and intentions. The ways people do this are often very complex and take a lot of skill to read accurately. Many people learn to do this unconsciously, but for you it will have to become a conscious and deliberate process. It's not at all impossible, but it will take time. Trying to learn these things without professional help would be very difficult, because the neurones in an autistic brain talk to each other in ways that are different.

Girls are better than boys.

Maybe that's why your dad is so protective

Females virginity is more protected

All lives are special.

Sons are special to mothers

Be grateful, not all are.

Yeah... It sucks when people take advantage of a good honest nature. 😒

I've been reading a book on sexual selection, by professor steve jones. Apparently, in a society in turmoil, families prefer daughters, and in a society that is prosperous families prefer males.
