Self-absolution. I understand it but it is a logical failure.
Should anti-LGBTQ fanatics who are absolutely convinced that they are morally superior be able to discriminate against LQBTQ people?
Should anti-abotionists who are absolutely convinced that they are morally superior be able to harass and threaten women making the most difficult decision of their life? Should they be allowed to fire bomb clinics? Shoot abortion doctors and nurses?
Should white spremacists who are absolutely convinced of their racial superiority be allowed to refuse service to people of color? Burn crosses on lawns? Hang people of color from trees by the neck?
Where does the vegan fanatics self-absolution end? Fire bombing restaurant? Pipe bombs wrapped in nails in crowded restaurants that serve meat?
The ability to self-absolve is very VERY dangerous. It permits fanatics to justify any ammoral horror in the name of their mistaken moral purity.
