I don't recall them insulting black children. Even though there wasn't a black child of the President of the United States at the that time, I can't imagine Archie Bunker referring to them as a "family of ghetto trash" and "ghetto thugs".
Of course he didn’t. You are right.
Once again, you refer to a handful of posts out of over 160. Not nice, for sure, but not the intent of the thread or indicative of the overall tone.
