“Nondiscrimination” (for example by nationality, age, sex, etc.) is generally a good idea.
But it can be taken into an absurd: I am weak so I am discriminated by heavy lifting championships, as I don’t have a prize which strong people receive. This is a discrimination by strength.
In comments to this post, please discuss how to define discrimination more exactly, in such as way not to lead to an absurd like above.
This discussion may have or not have political consequences, but I am personally puzzled how to define discrimination exactly and wish to receive an answer.
