I have been at great pains not to say that

You failed:

"open your eyes to the possibility that black male Nigerians (for instance) are more likely to commit fraud."
And your copper conversation:
"I asked him if any ethnic group was more likely to be found commiting fraud here and he instantly replied: "Oh god yes! Nigerians, they're notorious for fraud Just ask any dss fraud investigator!"

eh? read what you just wrote. say that again?

I meant arguing against.

So you are saying that Nigeria is corrupt!

I've lived in Nigeria.........yes i am bloody well saying Nigeria is corrupt country.

So what's wrong with me saying that Nigerians seem to go in for a lot of fraud?

Theres that victimisation mentality again. NOTHING. And i never said there was. Sheesh.

If Nigeria was corrupt under British rule and is still corrupt now under Nigerian rule, that would seem to prove to me that it is indeed the Nigerians (the constant) who are corrupt

Thats a pretty poor logic, especially seeing as the Nigerians under British rule werent the corrupt ones. Therefore, the Nigerians in your statement are not a constant. If the above simple, narrow logic is all it takes to prove something to you, then God help us all.
And its the British who instilled corruption in the culture of Nigeria, which is part and parcel of the current state of Nigeria. But thats a whole different debate entirely.

Or how about the fact that the Nigerian government is taking out newspaper ads to warn people about Nigerian fraudsters?

You say as a group, white males are more likely to commit acts of peadophillia.
So going by your logic above, because the British dont advertise warnings to people about white, male, hetrosexual paedophiles then that proves white, male, hetrosexuals as a group arent more likely to commit acts of paedophillia.
And the Nigerian government warn people about Nigerian fraudsters, because Nigerian fraud is a big problem and Nigerians, proportionately commit more fraud. None of this proves that any ethnic group is more likely to commit fraud. Especially, as i've already said; there is no Nigerian ethnic group.
