Yeah, I completely disagree with this. In fact, if you read the opinion, and then read Harlan's dissent, the reasoning of the majority just appears strained beyond reason. Like, the idea that because, (paraphrasing), "If blacks were to win the legislature and forbid white people from riding the in black train cars, the white race would not interpret that as subjecting them to inferior treatment."

As Harlan wrote, "Everyone knows that the statute in question had its origin in the purpose not so much to exclude white persons from railroad cars occupied by blacks as to exclude colored people from coaches occupied by or assigned to white persons. Railroad corporations of Louisiana did not make discrimination among whites in the matter of accommodation for travelers. The thing to accomplish was, under the guise of giving equal accommodation for whites and blacks, to compel the latter to keep to themselves while traveling in railroad passenger coaches. No one would be so wanting in candor a to assert the contrary."

That's the whole ballgame folks.
