The differences here are to do with intent.
The Islamic flag erected on the mountain side is directed at the gc’s and is intended to insult them. It adds insult to injury to an occupied people resulting from a brutal invasion and the theft of their lands. It is an utter disgrace because it is the symbol of occupation, is “state” sanctioned, is hateful and creates resentment. It is also being flood lite at night so the illegal regimes propaganda and message is working 24 hrs a day.
That Greek flag lordo posted is in a place hardly anyone knows about, is not directed at any group of people to make a political point or to insult them. It faces out to sea and given the fencing, Really could be on private property. It certainly has no malicious intent or is it politically charged. It is probably only a fraction of the size compared to the Islamic flag facing the capital of Cyprus.
