No it's not a term of friendship, and it's not in reference to homosexuality. It came from the 4/8chan and simply put on the end of words such as Planefags, Russiafags and any other topic that some anon might specialise in. It has and is used in a derogatory way sometimes, but not in the way you think.

Stop taking everything personal, and stop allowing mere words to define you, you can call me any names under the sun and I'd laugh at it.

PS No I haven't down dooted you either, I just think you are mistaken as to what it really means in certain parlance in a certain place.
