The one I posted took me about 1 hour. If I am in the mood of writing, I usually write very quickly and rarely I have the patience to review my own writing. Many obvious errors are missed even if I review what I just wrote many times. The subject and basic ideas usually brood in my mind for days or even weeks. Certain larger projects take years for me to commit to paper.
In deed the "Men" were white men only in the Declaration of Independence. That was the arguments used during the Civil War by many Confederates. Obviously that's wrong.
