He's being down-voted because it's whataboutism. It's no different than the 50 Cent Army that suddenly cares about Native Americans when the topic of the Uyghurs comes up. Yes, the red scare was bad, yes the US's treatment of indigenous people was bad. Everyone agrees about this. There's no school district in the US that uses a history textbook that says the Sioux deserved it and McCarthy had the right idea. The fact that similiar bad things happened in the past does not excuse them in the present. If anything it makes it more reprehensible that they happen today despite the example of what to do.
But there's no hypocrisy. Nobody is saying McCarthy was right or endorsing his tactics.
Edit: It appears I may have misinterpreted the initial comments sarcasm as a "if McCarthy could do it then it's fair game" rather than a criticism of modern outrage mob tactics.
> Nobody is saying McCarthy was right or endorsing his tactics.
You are correct that they are in fact not saying that; the hypocrisy is in then turning around and saying that cancel culture is right and endorsing their tactics.
