This whole Garak thing is just the thing where thirsty shipper fans with weird fetishes go "Look, these two characters of the same sex get along! Surely that must mean they are secretly gay and banging each other like crazy every night! *types another 20 pages of pornographic slashfic*"
It's wishful thinking and it is ruining a lot of good media. Look no further than LOTR, where Sam and Frodo's friendship is seen as a gay relationship, even though Sam later on marries that chick he was into at the start of the books. There were people in the 19th century, that thought women could not understand male friendship and that indeed "friendship" is something only males understand... this "They get along, so they are totally GAY" shit makes me more accepting of that 19th century nonsense more and more tbh.
