Cecil did not fabricate anything, unlike you, who has fabricated the use of “humane” by applying it to language as a synonym for psychology, and also fabricated the word “anim” to mean something that is animated (moving) but less than human (but broader than animal).
The word death is singular and uncountable when used as an actor or process:
“Death comes to us all.”
“I was facing a wall of death.”
“That’s death-on-a-stick, mate.”
However, death can also mean a single instance of an individual ceasing life.
“The death of my father…”
“The death of my mother…”
In that context, death can be treated as two separate instances, and thus given the plural, deaths.
“The deaths of my father and mother…”
That sentence might be used when the father and mother died at separate times from separate causes, rather than in one event, such as a car crash.
Other errors with your writing:
“Humane” is not a synonym for human.
There is no use for appending humane to language and using it as a synonym for psychology. You are making that up.
Also, “anim” is not a word. You made it up.
You accuse Cecil of making things up, but you are the one making things up.
If you are a native speaker of English, you need to beat your parents right now. And your teachers. And your neighbors, and anyone who interacted with you from birth to now. Your English is mostly comprehensible, but your grammar is weak and you have numerous sentence construction errors.
First off, you do not need a period after a question mark. Error on your part.
Second, Lena Meyer-Landrut - Wikipedia
She is apparently some sort of German pop star. I have no idea why John picked her as an example except that she is apparently someone in pop culture that you might have some familiarity and is a non-native English speaker. I doubt it has any other bearing on the conversation.
Here’s the problem, you are trying to tell us how you think we should speak, but you are claiming it is how English demands that we form the sentence.
You are free to make the case that we should always acknowledge the gender of babies. However, current English usage commonly allows that phrasing, so to tell us we are in error is to be incorrect.
As I said, it is annoying to be lectured on proper English from someone who makes as many errors as you do. Stop It!
