You are taking a defensive line. There is a lot of record that the paki ISI has many cels of Indian Muslims such as the SIMI. There can be no doubt about the antinational activities of SIMI. Even the original founder of SIMI (now a professor in the US) has said that he left SIMI after the ISI took over the organization.
Sure, Bajang Dal and outfits like that are communal. However, they are not antinational like the SIMI. While there are many good patriotic Muslim indians like Kalam and others, you cannot deny that there is a very significant number of Muslims are more pan-Islamic and pro-paki antinationals. Being defensive does not change this fact.
