When we use the term "partner," in the current vernacular, as in, "This is my partner <insert name here>" we usually mean that we are in a gay relationship with that person.  That's clearly anti-hetero and leads to hetero bashing.  We should instead allow heteros to have partners as well.  Why should gays be the only ones to get the "partner" benefits?  It is our right to have partners and no one has the right to deny us our partners.  Now we can obviously come up with a new word to describe a hetero "partner" relationship but why should we do that when we can just piggy back on an already perfectly good word.  All we have to do is extend its meaning to allow hetero "partners."  And if you disagree, then you are a heterophobe.
