Shiasm has served as a dishonest opposition to Islam historically and the trend is evident even today.The core of their Usool e din Tawheed and Adl have been contracted from the Mutazillites (whose slogan was Al Adl Wal Tawheed).The Shiites had joined hands with them then feeling that by forming alliance with them , they can broaden the opposition to Islam. I was reading a thread on a shia website about Javed Ahmed Ghamidi. Most of the Rafidhis were praising him for his stance and all this support for Ghamidi Sahib was due to the only reason that he has taken a line away from orthodox ahli sunnah so he must be supported for it. To give a break to the drama , a TV show of Ghamidi Sahib was aired during the days when the praise of Ghamidi Sahib in that thread was at the peak. Ghamidi Sahib in that show said that going to Karbala was an Ijtihadi mistake of Sayyidna Hussain ra. The thread suddenlt changed into Lanatullahi Ghamdi after that.
