I'm sure you're just as upset about Trump saying Jews that vote democrat are disloyal.
Whataboutism is a logical fallacy. We are talking about segregationist Joe Biden, author of the 1994 crime bill directly responsible of jailing hundreds of thousands of minority americans. Try to stay on topic.
Trump won 8% of the black vote in 2016 as well, obviously his remark was cavalier but he's not that far off. Biden also immediately apologized for it.
What a disgusting thing to say. Joe Biden could shoot someone in the middle of 5th Avenue, make a half assed apology a day later and people would still vote for him.
