What Philippine government is doing is a step in the right direction.  Anyone, whether he/she  is Imam or any ordinary citizen who is found to be instigating others by preaching anti-national slogans or sermons needs to be blacklisted and, if practical, ought to be deported or imprisoned without fail.  Other nations where these Muslim community leaders or so-called spiritual preachers exist should take a cue from the decision taken by the Philippine government to avoid the spread of terrorist activities.  Needless to say, these preachers prey on innocent people in the mosques and convert them into future suicide bombers.  These imams are the source of brain washing of innocent people. UK has lot of Muslim imams and community leaders who openly criticize the government and threaten to dethrone the present government and unfurl Muslim flag on the Queen Victoria's house.  It is shameful that the local government feels so handicapped in taking any strong measure to put muzzle on their faces and imprison them.  These fundamentalists are exploiting the soft tenets of democracy which ought not to be allowed to be exploited.  These brainwashed outlaws fundamentalist wherever they are should be muzzled now before it is too late.  If it requires to amend the respective Constitution, so be it.  If your country stops to exist, Constitution is a piece of paper which will be left with no value.  Therefore, protection and survival of a nation is of paramount importance than worrying about the pursuance of democratic principals which may be outdated.
