That's an oxymoron. You can't have "arguments of opinion" (at least not in the sense I have used those terms). Opinions are subjective preferences without justification. Arguments are persuasive positions with reasoned justifications. They're mutually exclusive. Opinions have no persuasive power, arguments do. You cannot use opinions to convince someone of your positions, and you cannot use arguments to justify subjective preference - by definition.
If you want to use "argument" as a synonym for debate or conversation or whatever, fine, but that's not what I'm talking about when I use the word here, so please don't use it that way with me so we don't get confused.
