Answer:
There's no proper noun in this sentence.
I think all men are not created equal because a terrible man could be born into riches and royalty and a great man could be born into poverty. Genetically men are not equal. There are people born with defects that will never make them equal to someone without them. Birth defects such as autism or down syndrome make it impossible for them to be the same as someone without those defects. Being born blind or deaf makes being equal and life so much harder. I do not believe all men are created equity.
