Attempts are being made to stop Somali-born Ayaan Hirsi Ali airing her views critical of Islam in Australia. As an atheist who suffered through a religious upbringing in an Islamic community, she speaks with authority about what Islam involves for women in third-world countries. It is important that we hear her views and engage with them. This is a country of free speech, not a land where we try to silence those we disagree with. Ali is under a death threat from radical islamists. Now a group of liberal Australian Muslims is trying to silence her. What is it that none of them want you to hear? Sign the petition to support her right to be heard.
