Not to interrupt the Sikh circlejerk, but there is good reason based on recent history to take a dim view on Sikhs that doesn't require being so ignorant as to mistake them for Muslims. Your average Sikh may be perfectly fine, but they have had a strong militant subset for decades, who notably have close relations with Pakistan's ISI, with whom they've cooperated to better enable their assorted terrorist efforts over the years.
In 1984 Sikh terrorists took over the Golden Temple, requiring military intervention by India (Operation Blue Star), the net cost being dozens of lives. Shortly thereafter and in response to India not giving in to the violent demands of the Sikhs, two Sikh bodyguards assassinated Indian PM Indira Gandhi. The next year, in 1985, Sikh terrorist group Babbar Khalsa blew up Air India Flight 182, killing all 329 people on board (with another bomb on the ground killing two more airport workers). The violence continued unabated but on a less visible scale into the early 1990s. By October 1991, they were killing 20 non-Sikhs a day by the various Sikh terrorist groups in the Punjab. India mostly crushed the major terrorist entities and curtailed the violence, but a number of Sikh terror groups exist in a weaker, more decentralized form to this day, and there has been increasing violence and separatist agitation in the past few years. Given their history, and the fact that much of the financial and logistical support for these terrorists came from Sikhs living in Canada and other Western nations, the unfriendly view some of us have of them is easily justified.
Now, I don't claim to be familiar enough with Sikh theology to speak on how it compares to Islam. It may well be the case that their violence is not religiously motivated, and that the real issue is with a nationalist political identity that is extremely violent and seems to be heavily interwoven with religious observance by a misguided minority. But Sikhs are certainly not the problem-free minority some here assume, whether because of theology or certain secular beliefs that've been woven into their identity.
