Good to see this issue being kept alive by Gerald Tan from Al Jazeera. I have had close contact with the Temuan of Ulu Selangor over the last 20 years and can attest that this isn't restricted to just Pahang. It's a national push to get all the Orang Asli to convert to Islam.
In my area, the JHEOA (Orang Asli Department) not only try to force the Temuan to become Muslims, but also to vote for BN at every opportunity.
I believe that there are only about 300,000 Orang Asli left in Peninsular Malaysia and these are scattered around the country in a total of 18 tribes. Even if all the tribes combined together to demand the right to live the way they prefer and still partake of development, they would hardly pose a national threat.
Just another example of how insane the Malaysian government has become and how intolerant they are of anybody different.
If you're interested in learning more about the Orang Asli I suggest you visit the Centre for Orang Asli Concerns
