Gender-neutral words defy the natural order

I would like to know just what the people who are trying to change our language to become gender-neutral are all about.

If I remember correctly, humans and other species are made up of male and female. What words are going to replace gender-specific words such as mother, father, son, daughter, brother, sister, etc.

What about procreation? Without two genders, we cannot procreate. Even in a test tube, a male and female are required.

This whole thing is absolutely ridiculous. Please find something worthwhille to worry about.
