No, Jesus Christ No.
Post this to your TD, senator, representative or any other useless prick who masquerades as a useful member of humanity.
I'm in a heterosexual marriage which is a lifelong commitment  that I entered into willingly and I want you to extend the same benefits and rights to anyone who wants to enter willingly into a lifelong commitment regardless of their age or gender. My marriage does not need protecting from similarly committed couples but I damned sure don't want a bunch of populist whores like you dictating what is and isn't marriage based on what you think will appeal to the nasty inner core of the voting public.
Screw you, seriously - screw you, if you believed for a second in equal rights for everyone then you'd be fighting for this instead of keeping quiet and hoping no one asks you a direct question.
 Whatever I think about religon, I made a vow to whatever it is I believe in and am convinced is out to get me and I take that very seriously so your version of "lifelong" may vary.
