It's funny that the OP recommended taking 77g of proteins per day (1g per kg for a 170lbs person), while you say that he is recommending too much protein, then proceeding to recommend 60-100g.
OP recommended 1g/pound which is more than double that 77g for a 170lb person. Not saying that the comment you responded to is necessarily right, but they were talking about significantly higher amounts of protein than you.
Edit: I mixed the units.
