if one looks to, and trusts in, the definitions of others; one is bound, or a slave, to said definitions
if one looks to, and trusts in, 'case law'; one is subject to the whims and opinions of those who create 'case law'
you use '12 USC 136' as a means to understand what man is, or what others may point to as a definition; i only use, and trust in, one source for the definition of man...
Genesis 1:27
So God created man in his own image, in the image of God created he him; male and female created he them.
by the way, the 'Constitution'
is nothing more than a piece of paper
and
people are more than one man collectively
what source are you using to etymologize the words used by others?
shouldn't you utilize sources
prior to the writing of the 'Constitution' if you wish to offer an opinion regarding the definitions of words used in said document?
do you claim to know the hearts, minds and intent(s) of the creators/writers of that document with absolution?
if you choose to accept "man means animal"; so be it, and i hope it works out for you
