How are you going to talk about him still argueing when you need the last word.
Needing the last word is a moronic concept.
If someone argues a point a rebuttal is logical. The only ones who argue "your just trying to get the last word" are the ones who's logic has holes (that they don't wish discovered). So they encourage the other party to stop the argument before they do discover the truth.
If you have a clear understanding and proof to back up you're logic then it is illogical to stop arguing untill that point is conveyed. Otherwise false information is conveyed.
That said when you are arguing a point proven false, it is logical to concede.
However, all audioholic has done is either dispute viable (however, minimal, evidence.) Or posit an argument as if I was defending it 3 years ago.
In the case the viable evidence is as follows:
1#: my personal testimony including information of the testimony of others.
2#: the physical likelihood that the situation I present is actually true.
3#: the lack of theoretical or empirical evidence that suggests otherwise.
He is arguing on certain fallible principles:
1#: That the person I was 3 years ago was vulnerable to attack as support for an argument.
2#: That I am the same person I was 3 years ago.
3#: That the opinion evidence of several professionals who have a different goal than I, have applicable interests and information in the matter which is ,in essence, subjective. Thus their course of action can be looked at as a model to judge mine by.
4#: that there is any evidence, theoretical or empirical that suggests the point is valid.
Since these premises are obviously flawed in one way or another he is simply finding eddies which he can plant is argument by arguing in a circle. It's like interjecting the question "does your mom know you are gay?" into an argument. All it does is stall the inevitable realization that if your logic was viable, you would be able to present an argument free of fallacy.
