@JeffreyEqualityNewma,
Why can't you just change the definition of marriage to fit polygamy? You're already doing that to fit homosexuality. Marriage has been EXPLICITLY defined as being between a man and a woman. You simply attempt to change the definition to fit homosexuality. The polygamists are simply going to argue why can't you change the definition again to fit polygamy?
Not to mention, when you state that it's okay for someone to marry a homosexual partner because they're not hurting anyone and they are in love with their partner and you have made bisexuality an acceptable way of life, then what argument do you have to tell that bisexual that they can't express their love through marriage with their partners? They love both of their partners equally so why shouldn't they be allowed to marry both of their partners? Who are you to deny their rights and refuse to allow them to express their love with one another? Who are you to say that they can only visit ONE of their partners in the hospital? Who are you to say that only ONE of their partners can receive healthcare benefits? They're going to argue that you put an undue strain on their relationship with the people they love because you are forcing them to choose between the people they love.
In otherwords, they're simply going to use the EXACT same arguments the homosexuals are using to justify their position. And if you accept the homosexuals arguments you MUST be willing to accept the polygamists argument when they are making the SAME argument. That's part of the problem with accepting homosexual marriage. You put yourself in an INDEFENSIBLE position in regards to other immoral, unjustifiable activities like polygamy or incest.
I'll ask you again... if you are willing to make the argument that we should change the definition of marriage to fit homosexuals... then on what grounds do you then state to the polygamist that we're not going to change the definition of marriage to fit them? Why not change the definition of marriage to fit a Father and his 18 year old son that want to get married?
Why? Because you're a hypocrite and you don't actually believe in equality. You ONLY believe in equality when it's beneficial to your argument. Therefore you do NOT believe in equality and for you to attempt to use it to justify your position is fallacious at best.
