Blaming ALL whites is a way to avoid blaming SOME whites. In the US, it was the Democratic party that was pro-slavery. Better to blame whites that to blame Democrats. The same with Indian removal, segregation, Japanese American internment. It probably works the same way in Europe.
And it was the *LIBERAL* big government Republicans that pretended to care about slavery. (See Corwin Amendment where they voted to protect slavery forever.)
What they all cared about was money. Washington DC was a corrupt sewer since the 1820s, at least.
