I don't think its just in islam, I think its just in general all over (I'm not talk about a passing comment) No one likes to be accused of something most especially if its not the truth.

But, What if that person is right ?

It has nothing to do with likes and dislikes, Islam has a diffrent set of moral code than the rest of the world with different consaquences according to islamic teachings. If the person is right about the matter then there is a way which the issue has to be aproached, going about it the way people have been doing here is itself compounding there problems with Allah. Public Humiliation and display is not acceptable, as well as calling someone names. we are not talking just about the person being right or wrong here, that is one issue.

Staying away from celebrities and the tabloids - Where ?

I don't think its taken as a grain of salt, those who believe are wrongly accused can take the offender to court on defamation, even celebrities to do this.

What are the moral not legal consaquences for such things in Australia. I live in Australia people get into fights and dont give a second thought about what Allah might think of such behaviour or what reprecutions it may have apart from the imidiate.

How is it a sin if you are wrong ?

Where is the qur'anic support.

do you consider the way people aproached the issue is correct? it is a sin for a muslim why do you want to see the Quranic evidence will that change the way you look at things? i dont see a purpose in reaserching this matter for you and i dont have the time, maybe another forum memeber can Quote for you the relavent information it is common knowledge.

Without wrongs and errors we wouldn't learn what is right.

No since people use scociety as a basis for what is right and wrong not Allahs revelation. How do you know something is wrong if Allah hadnt told it is wrong?
