You just based your opinion on other's opinions
Is that your opinion, or fact? Because I'm pretty sure he's basing his opinion on facts as well. All of it is authoritarian information, and not empirical, but I think we can still accept a lot of it as "fact" none the less.
So you're saying that when the facts come out, if the opinions you've based your own opinion on don't change, you won't change your mind.
Again, your opinion of what he meant? Because my opinion is that you had a little reading comprehension fail, don't know the meaning of "revoke", and/or intentionally misrepresenting your opponent (in discussion terms) with a position you know he doesn't represent so that you can continue to argue.
What I think he said is that unless the forthcoming facts of the case revoke (See: abolish, countermand, disclaim, dismiss, repeal, void, withdraw) his earlier obtained opinions, than he shall continue to hold the same opinion. Which is completely reasonable, because without new or contradicting information, why would anyone change they position?
And then you wonder why I'm a little annoyed at people who state their opinion as fact ? Seriously, fact is fact. Opinion is opinion. Innocent until proven guilty. Chen and Co. have yet to even be charged with anything, but in your mind, they are guilty and you base this on opinions published everywhere (because the facts sure don't support this guilty verdict).
English western culture tip: Most people speak in opinion, and when stating a fact they add the word "fact" or "truth" to the beginning or end of they statement. I.E. opinion is the default. However it should be noted that stating fact and truth in the current culture is an unpopular thing to do, so even when you try and state a fact or truth, people dismiss it as being just your opinion. Perhaps this will help you understand why we, on a forum for discussing ideas, keep running around stating "facts". In reality, the majority of culture dictates that opinion is the default stance.
You are entitled to your opinion. You're even entitled to not change your mind when the facts prove you wrong. But to pretend your opinion is factual because of your interpretation of known evidence (which we don't even know if it is court worthy or not at this point) and other's opinions is wrong.
Ethically or legally wrong? Because it certainly isn't legally wrong, and ethics, well, they are a matter of opinion these days. So now we're back to square one. Are you trying to state that your view of ethics is a fact?
