Lordy. That's a nicely worded piece of...something you got. Maybe reply with something like 'Thank you for your response, however it seems we must agree to disagree on this matter as I do not believe that love is defined by gender or any such borders and that it is in fact far more important that the human race express their capacity for love - in whatever form - than suppress it by conforming to societal prejudice.' And end it with, 'Without prejudice, Erastes.' That's what I'd say at any rate.
