I wouldn't say he's wrong. Calling someone a man implies they have at least some degree of maturity. Something we can all agree most lefty adult males are lacking in. But of course, that's really not what he means.
There are many things a male human can grow into that are not a "man" - he can physically mature without mental development, growing into an oversized child; he can physically mature while regressing mentally, growing into a cuck, or he can cease to be human entirely by choosing to become a communist.
