First, you’re getting the quotes wrong. Second, you’re taking them wildly out of context. Third, you’re confusing mistakes in speech with policies designed to harm minority communities.
And regarding Robert Byrd (if you didn’t know, that’s who your last sentence refers to), he was a segregationist that did teshuva. He spent the last 50 years of his life repenting for his segregationist sins and working to undo the harm that he did in the 40s and 50s. This is well known. I think that deserves praise. When you see a ger tzedek or baal teshuvah who is a yieras shamayim living a Torah life do you first remind him of when he ate cheeseburgers 30 years ago?
