SIS ban issue

It is reported in 'The Sun' today that the PAS Shah Alam MP and division head admitted that he overlooked the resolution to ban SIS.

The resolution as reported by the Star "to call on the National Fatwa (Edict) Council to do research on SIS, which is promoting liberal Islam, and ban the organization if its views are found to be in conflict with Islamic teachings and to rehabilitate its members"

First, I thought Islam is a liberal religion.

Second, even if the view contradict Islamic teachings (and who should be the arbiter?), should the authorities engage an intellectual discourse with SIS rather than banning the organization.

My last posting in my blog touched on Islamiphobia or paranoia. Who can blame the non muslim when the paranoia originates from within.
