In the post you quoted, a series of random allegations about Shia Islam of which not a single one is factual. This subject gleans their "information" about Shiaism from propaganda websites created and financed by the US- and zionist-allied Saudi regime and its minions, which are tailored to appeal to frustrated and easily manipulated folk. Same old, worn out, shallow drivel. The subject obviously never conducted independent research from authoritative sources, never bothered to investigate what high-ranking Shia ulema actually teach their followers.
Anyway, beautiful debunking. Let me contribute to trashing the obvious disinformation you addressed last (where they claim Iranians in general curse the Prophet's wife):
