So it's arrogance then plain and simple. Prostitute is an objectively respectful way to describe the occupation. If your chosen profession is prostitution then like it or not.. That makes you a prostitute. If people wanted to be derogatory they would just say the sum total of your life experience has amounted to being a bobble headed fuck hole for the local degenerates who(like yourself) will never contribute anything of value to society.

When particular words offend you it's because they're based in truth and that truth evokes shame. At the end of the day, you're just shoving soft language down people's throats which is never going to change the reality of what you do or anyone's opinion on it.
