Leah Remini's Scientology War with Kirstie Alley -- I'd Rather Kill Her with Kindness

exclusive

Ex-Scientologist Leah Remini's taking the high road after Kirstie Alley called her a repulsive "bigot" on the radio -- telling TMZ, she only wishes the best for people ... even if they hate her back.

Leah was out in L.A. last night when we asked about Kirstie's recent Howard Stern interview ... when Kirstie bashed Leah for criticizing Scientology after leaving the Church.

Kirstie called Leah an anti-faith "bigot" who picks on Scientologists for no reason ... then said Leah was her "enemy."

But last night, Leah was stoic ... until we chatted about Kirstie's new sitcom. Check the clip to hear what Leah really thinks.
