Same as today any writer can write about general majority of Sikhs being non-turbaned, drinking or some smoking. 100 years later we cannot simply believe that they were the actual Sikh. Just like in past there were actual Sikhs who followed guru path and some who were on and off that path with their weakness. Maharaja Ranjit is the perfect example of a Sikh who was not a Sikh in our guru eyes with his lifestyle.
in the old days sikhs used to be very harsh towards ex sikhs, the christian convert sadhu sundar singh used to have sikhs throwing stones at his houses, not saying that we should do that but our attitudes have changed a lot, changed so much that sikhs have become way too tolerant. i dont know how long this change towards liberalism is gnna continue but it needs to stop
in the old days when the british used to convert sikhs to Christianity in punjab, sikh preachers used to go out there and convert the same amount of christians to sikhi! iv read about it this happened a lot in the late 19th century and early 20th century. there was a case where sikh parcharks converted a lot of christians from haryana to sikhi in response to the british converting poor sikhs to Christianity in amritsar.
now sikhs have become to flipsy floppsy
