Let me know when you start doing that, then. I'm sure the Palestinians appreciate that they're the only ones to be genocide by your direct choices, I'm sure they're happy you voted for "less genocide" instead of no genocide.
Palestinians seem to think otherwise, at least the ones here. But I guess you wouldn't be a white savior if you didn't override their voice, like you do with pretty much anyone of color that doesn't vote dem.
If we're being pedantic, we can go bank to the Magna Carta, or Hammurabi as the beginning of civil rights. But you're the one who set the 80 year mark, which coincides with the 20th century civil rights movement which was a distinct movement from the abolitionism of the 1830s.
But you're wrong either way. The 20th century civil rights movement was absolutely supported by Democrats, or was Lyndon Johnson not a Democrat when he signed the voting rights act?
And the 19th century civil rights movement was championed by the pre-switch liberal Republican party. So yes, the liberal party has been supportive, if not integral, to civil rights. You'd have to be pretty poorly educated in US history to be ignorant of that fact.
