"It has to be understood as something that has been and is produced and praised in history and culture. It is the specific way we (or rather, a relatively "out" minority) have found of coping with and resisting our oppression and our peculiar  situation as "invisible" stigmatises people" 

(Jump cut, no. 18,  August 1978, Richard Dyer, A review of contemporary  Media)

This basically suggests how being open is seen as a positive thing perhaps connotes bravery and strength for being able to actually come out about there sexuality and 'praised in history' suggesting how views have possibly changed. However also suggests how oppressing there sexuality creates a boundary making them feel 'invisible' by there own choice and then it merely provides the conditions in relation to which oppressed people create their own subculture and attendant sensibility.
