Wow, this is an ambitious topic to be sure.
Honestly, what is equal?
Can anyone be truly equal to another person?
There will always be barriers, exclusions and exceptions for everyone.
I like the Oprah Winfrey story. (Hate her politics) She was abused in many physical and mental ways, was a black woman when even other blacks gave black women little status, and entered the realm of reporting when few were able to ever make it to the big time.
Many years later, she is the most wealthy woman involved in the media today.
Was she more or less equal than any other black woman?
Why did she succeed where others failed?
Equality is an illusion, the real differance is who is creating the illusion, you or someone else.
