You are allowed to renounce

Penang Syariah Court allows Muslim converter Siti Fatimah Tan Abdullah [real name: Tan Ean Hung] to renounce her faith back to Buddhism. Progressive decision, what is the point to incarcerate her body when the authority will fail to control her soul on her decision to go back to Buddhism. Better let her go rather than make her life mockery and tarnish the image of Islam.
