I don´t agree with the red letters.
I have known some who were protitutes, killers, drug abusers, etc. and have changed from the inside out. That is an useful reference to know the person we are going to deal with but, with some human bias, these could be prejudices and their stains.
I respect your opinion but, I´m aware many could le to hide that thuth easily and, doing it, became liars and cheaters.
I believe, if a person loves, she / he will be open as a flower, to see his/ her deepest real beauty (and ugliness).
