Nobody deserves to be marked unlovable based on the way they are born. Period. If someone has already hurt you personally then that's different: an individual is different from a category, actions are different from hypotheticals, and trust is different from compassion. I'm not saying a person's past actions should be ignored. What I am saying is that everyone should be considered based on their own individual choices.
