I see way to many desi Sikhs that insist that caste is an important part of heritage...even among Sikhs that follow a strict rehat. Findings in astrological or numerological readings are followed more staunchly than Gurbani readings. Some keep pictures of their gurus, many even bowing and praying to them, or keeping cell phones near them "in case Guru needs to make a special call." Others have kitchens are obsessed over to the brahministic standards of succha...sometimes going as far as saying that succha is kept so the first bowl of food can be offered to Guru Sahib.
To these desis, these habits are an important part of culture. To a westerner, they are are ludicrous.

But there is something much more sinister behind this...and it isn't the mere differences between East and West.
All of these trappings play right in to the hands of the extremist Hindus that are always looking to justify their view that Sikhism is simply a sect of Hinduism. These culture-worshipping Sikhs are playing right in to their hands.
