Within reason.
The main reason integration was instated, was to take the black dollar to get more money, while simultaneously suppressing the strengthening of the black community because now you're taking our money. If we stopped soliciting their businesses by in large, then it would make a much stronger impact than protesting or praying, because if it's one thing these corporations don't fukk around with, is someone fukking up the money. Hopefully someone would then get in the police commissioners ear, and tell these pigs to stop murdering blacks so eagerly, because they want the black dollars. Keep in mind, black people spend billions of dollars in this country every year.
But I see that petty little quip you made probably made you feel smart, rather than trying to understand his point more thoroughly. This oneupsmanship game we like to play, along with protesting and praying, gets us nowhere.
