We are arguing the whole of your position, that it was a "good" point that it should be banned because it is "unnatural", you said you would begin with this point as the central theme of your argument.Natural and moral are two separate issues. Which one are we arguing about?
So, now that we find that it isn't "immoral" because it is unnatural do you want to move on to another "point" and continue the conversation? Or do you think that your total failure to connect "unnatural" to "should be banned therefore" is somehow something worth continuing?
