Whoa at this becoming a huge mess. Why can't people just share their opinions without always trying to tear down someone else's?
I am personally not for the term "partner". For me, a partner describes a relationship that is not on the same level as a relationship based on love. That is just my personal connotation of the word. I see a business partner, a school project partner etc. not a partner in life.
Boyfriend, girlfriend, husband and wife are more definitive and express the intensity of a relationship, I feel. If I want to be in a relationship with a women, I will call her my girlfriend, or wife if it progresses to that stage. The same for a man. The idea that calling your male lover your "husband" insinuates that you're his "wife" is abhorrent to me. There is no reason why a relationship can't be husband/husband or wife/wife.
I personally have never seen or heard straight couples use this term "partner" as the main descriptor for their relationship. Perhaps in passing. But as others have said, it's generally man and wife, husband and wife etc. not partner and partner or partners. That's definitely more something associated with the LGBT community in order to not emphasise on the fact that they have a same-sex of different-sex partner that isn't straight.
