Why Islam still is a taboo for non-muslims

Malaysia is not a country that lacks controversies from the Mongolian affair, multiple corruption stained projects, missing PI, dying detainees under police custody to body snatching at the hospitals. One that seems to make the headlines frequently is of conversions of non-Muslims under dubious circumstances.
Today a mother of two claims that she was unwittingly converted to Islam by state religious authorities when she was a child at the age of 7 while residing in a welfare home in Kepala Batas,Penang.
S Banggarma, whose Muslim name is Siti Hasnah Vangarama Abdullah, said she discovered this when she went to register her marriage in 2000 when she was told that she converted to Islam in 1989!
She was born as a Hindu and her birth certificate stipulates that she was born on Aug 13, 1982 to plantation worker B Subramaniam and Latchumy Ramadu. She was apparently converted to Islam before a religious officer representing the state Islamic council in 1989. However, Banggarma could not recall the incident and claimed that she was always praying and living like a Hindu even while in the welfare home.
During the press conference, Banggarma also revealed that she was brought to the welfare home together with two of her elder brothers and a younger sister when they found them sleeping on the roadside in Kepala Batas by welfare officers.
I just could not understand how someone at the age of 7 years would understand about religion and why is that some overzealous religion officer could convert a child who is 7 years old? Is there a promise that if they do so, they are assured a place in heaven?
Until and unless the Muslim community does not stops such an act, the non-Muslim will forever be uncomfortable of Islam and the Muslim at large.
