Natural inequality is when inequality is caused by something natural and is harder to control and I will give you some examples.

Some people are Bourne good lookout while others are Bourne less good looking.

Some people are Bourne rich while other's are Bourne poor.

Some people are Bourne into dictatorship while others are Bourne somewhat more free.

Artificial inequality happens when inequality is created by something done intentionally and is easier to control and I will give you some examples.

Mandatory military service for one gender but the other doesn't have to do it.

Scholarships given to one gender our ethnicity but denied to the other gender our ethnicity.

Employment opportunities given to one gender but denied to another.

The problem with feminism is that it creates a lot of artificial inequality that favors women and discriminate against men like female only scholarships and male only drafts and female only work place programs our diversity hiring.

Natural inequality is easier for people to accept and handle but artificial inequality causes problems on a societal level and a personal level.
