Nobody talks about the trees anymore. You should read the description of the campaign:
"But this is not just about a park. Before the park was the closure of an Ottoman pastry shop, the arrests of journalists, laws on alcohol sales, constantly changing school curricula. Gezi Park and the subsequent police violence on demonstrators were just the latest examples of a fundamental shift away from basic civil rights."
Don't forget that there is a major war occuring on Turkeys border and significant geopolitical games occuring. This isn't about trees anymore.
