They are calling protesters a "handful of students dissatisfied with election results". Less than 50% of protesters were students.
By they do you mean Western neutral observers and some of the most respected journalists on the planet (Associated Press)?:
The protesters, mainly students, stood outside the National Assembly building for the sixth day in a row, blowing whistles and banging pots, AP reported.
So, they read this and they think that protests are small in scale and unimportant.

One guy won the election, with 55% of the vote.
Next guy had only 16%.
This is a landslide of insane propotions.
Look I don't even care about this election, or whatever happens in Serbia. But this idea that these protestors are being oppressed and censored is ridiculous.
Nobody is censoring them. The majority of Serbia, let alone the world, just doesn't care.
