To understand the left's logic, we must examine what I call the socialist victimhood "food chain."
While there are always quite a few "victim" groups (i.e., "oppressed peoples") on the Socialist Animal Farms of the world, some groups are far more important than others.
As the examples above demonstrate, a theoretically "oppressed" culture or religion's status as "victimized" allows (nay, it demands) the consequent suppression of any uppity victim classes subsumed within it (e.g., Women or Gays) who try to rise above their assigned place in the utopia to come.
From the perspective of the socialist utopian, what matters more than Women's rights or Gay rights, are the rights of the designated "oppressed culture." The dogma of multiculturalism trumps the lesser dogmas of feminism or gay pride. This is probably because for the socialist utopian, might makes right and the needs of the many always outweigh the needs of the few--and the few better remember that fact, or else.
