The simply do not agree with you about the definition of when a human becomes a human. That is a reasonable thing to disagree about.

When what becomes a human?

There is no rational, ontological or scientific basis for re-defining who is a human being, and your self-contradictory use of the word "human" proves it.

Cordially,

You jumped to quickly to square number two. Forget "re-defining." Start with "defining." You are smuggling an assumption that YOU own the original definition. Prove it.

Perhaps he thinks a human "becomes human" when it is self-sufficient.

...around age 2 maybe when the little buggers can run around, feed themselves, etc.

A newborn infant will die without intervention (feeding and "upkeep").
