you are aware that there's still people alive and kicking who were kept from voting, kept from getting loans, kept out of supposedly public establishments, and so on and so forth, right?
it was less than 50 years ago, ya know.
and furthermore, you know there are still far more people alive and kicking who did deny those meals, those services, those votes (and still would if they could), right?
closing your eyes and saying you've never seen it happen doesn't mean it hasn't. these people who it happened to are still alive even. that's how recent this is.
