Are you bringing religion into it? I wasn't. My arguments have nothing to do with religion and if you think attacking religion is the only path for your argument, then you are discussing this with the wrong person.
Any your last question has nothing to do with the discussion. Its a bait question, to which you have talking points. It is irrelevant to me.
You're not bringing anything into it. You have no argument. You have stated that the definition of marriage should stay what it was, despite being shown it's changed countless times in the past several centuries.
You cannot provide any basis why changing the definition would be harmful or negative in any way.
You have no sufficiently supported any claims you have made and ignored or diverted when proven wrong.
You simply believe that the definition of a word shouldn't change because that would involve the definition changing. Please elaborate if your argument is more complex than that.
