Well, i understand how it can be so frustrating to lose such an important and close game. And I can understand a little bit more now why do you feel cheated and "robbed".
I just dont want, like i felt from some (only some) people, that anyone feels Portugal can only win games due to referee's "biased" decisions. Although the referees did some bad decision like sending off Ovchinnikov against Russia, i do not believe that referees at this tournament are being biased, I believe they do their decision actually with good intentions. Again I say, they are human and "Errare Humanum Est" (I believe this is how its written

i dont speak latin thou).
Portugal played well against Spain and against England (probably better against Spain imo), and won their victories with hard work and great motivation and confidence.
Also, i feel that many players dive a lot and I criticised that in the portuguese players, but english players do it as well (like Gerrard and Beckham, just to name some).
The english Premier League is certainly one of the most enjoyable leagues to watch, and i like that there are so less free kicks given than here in Portugal or Spain, but that is not cause we are more violent than english or something, it just that there's a different mentality (imho football might be less appealing like this, and some players do take advantage of the referees' conducts to illude them, but its not like the refs mean to destroy football by doing this). But there again UEFA has no intention into destroying football, it's just that players physical integrity should be protected, they are after all, what makes footy so beautiful.
