For example, let’s say you meant your co-workers speak with poor grammar and are difficult for customers or clients to understand. That’s not speaking ignorantly. That’s just speaking poorly.

Now let’s say a racist white guy brands his co-workers as being guilty of “ignorant speaking” when he really meant his co-workers speak poorly. In that case, the racist white guy would be speaking ignorantly because he would be speaking about something of which he had no knowledge, namely the correct definition of the word “ignorant”.

Just an example but do you see the diff?
