Why the Portugal hate on season 4???

I was pretty shocked by the comments throughout the season about Portugal. "Why go to Portugal when there's Spain" calling Jambon what is presunto in Portugal and speaking Spanish and making it pass as Portuguese. As a Portuguese living in a foreign country and having been insulted a lot for being Portuguese all through my childhood and teenage years, it hurts to see the ignorance and prejudice perpetuated on one of my favourite shows. That's all.
