Portugal is full of decent people
But they have been fed false information
See the above video for proof
I remember asking for a sub-forum in Portuguese, so that we could get Portuguese people on board. I did not realise at the time that most Portuguese people speak high-quality English, so that venture was not necessary.
The stats for my blog show Portugal as one of the highest readerships, so there are people in this country who are interested in the case, but not very many. I have never seen any stats for this forum, but I would predict the same pattern.
You may be making a fundamental error in your analysis. Of the 4 media experts I met around the 10th anniversary, the issue I had was in simplifying things down to the basics. They do not spend hours immersing themselves in the details of the case. That is not their job. They are there to make sellable product.
I also dealt with Panorama, and that was different. They credited 2 researchers, one of whom has been associated with the case for many years.
I doubt very much that the great British public contains more than a few people who are well-educated on Madeleine. And I would be surprised if they were nearly all McCann supporters. But decency does not come into it.
