This was soon followed by a guest appearance in It's Always Sunny in Philadelphia, where she portrayed a femme fatale in the role of 'Tammy', who through a combination of seduction and threats manipulates one of the main characters.She also has a small part in an episode of Standoff.
So in short, sexual attraction based on looks IS discrimination.
The only difference is that society places race, just another pointless physical attribute of no more import than height or hair colour, as a separate issue to be treated differently, for good or bad.
This includes weight, smell, hair colour, eye colour, height, penis size, accent, voice, this even includes gender, sexuality or any physical attribute.
The problem is that people start equating certain physical attributes as more important than others, never dating a fat person is now fatphobia, never dating a feminine person is femphobia, and of course never dating a black person is now racism, but height for example is 100% okay to discriminate based on.
Discrimination is treatment or consideration of, or making a distinction in favor of or against, a person or thing based on the group, class, or category to which that person or thing is perceived to belong to rather than on individual merit.
