A group of them, fueled and funded by some corrupt politicians and other nefarious individuals, have indeed strayed away from their religions teachings and are trying their utter best to create interracial and interfaith conflicts. The Halal issue is only one of their strategies that thankfully seems have failed.
So far only ones to take the bait appears to be extremists and ignorant folks from both sides. Thankfully plenty of Lankans, from all faiths and races, are not only condemning their actions but going all out to ensure their attempts fail!
