In order to grow in holiness we have to learn how to see - ever more - more and more matters from a supernatural perspective, from God's eyes, not human eyes.

Some people read most events that occur -whether personal or in the cases you mention indirectly - from a human perspective, based merely on human characteristics or reasons.  In your case, racism & sexism.

I see matters occurring along a supernatural plane....I don't see whole categories of people doing things to others based on mere human characteristics...I strive to see individuals either doing or not doing the will of God....are they loving God, are they doing the will of God, are they striving to love others more, treating them as other Christs?  Does this or that person steal a work of another (not groups against groups)?  Is this person doing things out of love of God, are they chipping away at personal defects, vices, growing virtues of generosity, cheerfulness, etc. 

We're different, but we weren't always different.
