In urdu we also use 'Mauze' so i doubt if it is hindi word.It sounds like a persian one.Indians have problem prouncing words which end with sound 'z'.Just like Mumtaz Mehal became Mumtaj Mehal and now just Taj Mehal.
Sikhism needs neither a reformation nor a philosophy of free will. Reformations are for religions that are at a primitive tribal level in the first place. Sikhi starts off with Guru Nanak Ji feeding people langar, and preaching meditation of Satnam. If you start off with capturing war booty and sex slaves killing all the males, yeah, you need a reformation.
Philosophy is (mostly) for people trying desperately to understand the universe without real divine knowledge. These types of efforts are called ਸਿਆਣਪਾਂ in Gurbani. (You did you Japji this morning, right?) All of these sianapan don't amount to a hill of beans. We don't have the burning need for philosophy that Westerners do because we can obtain complete knowledge via simran.

it's my fault, i should have phrased things a bit better. Basically based on the data he gathered same sex couples are more likely to settle into a routine and are less likely to do things out of said routine (such as cheating, which according to the data he gathered was surprisingly low compared to straight couples).
By similar attributes I mean people like them in terms of personality and taste. In straight couples you can usually note a sort of polarity in the way they behave and their personalities.
Again this is based on one study, nothing official or on a large scale really.
