I don't go out of my way for attractive people and just ignore them
What makes you avoid helping attractive people?
So many attractive people do nothing, which is a real shame
Having judgements about various people is normal. However, you should never discriminate against a person because of the way that they look. Consider that everyone is an individual and have unique qualities, regardless of their appearance.
It is not a crime to not want to help an individual. If they were more attractive, they should receive help quicker.
Just because someone is attractive doesn't mean that you should judge them negatively. Appearances shouldn't really matter, but their character. How about helping someone regardless of their outward appearance, they would appreciate your actions no matter what.
