Why do parrots generally dislike female humans?

This is not true. Most of the time, parrots will bond with one person despite their gender. There are some birds who do prefer one gender over another (for ex. a male bird likes a female, a female bird likes a male human) but this is not true in all birds, and parrots do not "generally dislike female humans." That is just not true.

I read in a forum that when they look at humans they see the shortest person in the house as the person at the bottom of the flock so they are generally more aggressive to that person because they are trying to assert their position in the flock.

I guess more often the shortest person would usually be a woman or a child so I guess that could be why it appears as though they are more aggressive to females.

it ought to look like it ought to yet God will under no circumstances enable it to flourish only as He stopped it lifeless in its tracks with Noah's flood. also technological expertise is on the verge of proving by ability of mistranslated scripture contained in the Bible that the God Yahweh exists. How will it then be a chance for atheists to exist in any respect now to not indicate become the overall public?

That is not true they do not pick gender.

They don't.
