If you fail to have pride in your own heritage (call it tribe, culture, ethnicity), then those of other ethnic backgrounds that do have such pride and cohesiveness, will inevitably eat you alive and take away your political power, wealth, and rights.
The trend of PC is about giving minorities the right of supremacy while the majority gets their rights squashed as a victim. Cuckservatives is the perfect descriptor of those that have sold us out.
I wish more understood it as perfectly as you do.
