Caste as alibi?

Kalyan Singh has very cunningly distanced himself from the Babri Masjid demolition ever since resigning from the BJP. The latest statement is :

"I was told that nothing will happen (demolition of mosque)… there was a conspiracy by BJP behind it. Two big leaders who were kar sevavadis, had given to Supreme Court in writing that only a symbolic kar seva would be held there (in Ayodhya),"
"Kya Muslim nahin chaahte hain ki BJP ka naash ho? Tumse zyada to Kalyan chaahta hai ki BJP ka naash ho. Maine BJP ki kabr khod di hai, aap us per mitti daal dena is baar." (Don’t Muslims want the BJP destroyed? More than you, Kalyan who wants the BJP’s destruction. I’ve dug the BJP’s grave, this time ensure you seal it with earth.)

Looks like this move will make way for factionalism in BJP, as it happened to Congress a few decades ago.
But I find Kalyan’s stance totally disgusting. How can one turn a blind eye to what was happening (Babri demolition) then and now when the elections come around, one just says that one was targetted due to one’s caste? Talk about conspiracy theories!
