It seems that you had to post this anyway. Had you bothered to read by post you wouldnt have since I had made it clear that there is a big difference between cursing and abusing. I have heard the first couple of minutes of the link, and it clearly falls into the second category while the enemies of Shias have been trying hard to present abusing as curse (la'an).
If you would listen to it, you will realize that it is stating exactly what you are saying, that is, about the difference of the two.
