In my opinion, no. I was in Gezi square during the 2013 protest. The square was packed as the Turks were railing against the increasing islamisation of the government and civil policies. The protest was calm and civil, speaking to a range of Turks at the time it was clear that anti-government violence was off the agenda. In the intervening years you can google news of Erdogans mass arrests of senior military officers; police; teachers and public servants. Erdogan has effectively de-skilled his opposition. The recent failed coup showed a debilitated opposition.
As to 'popular' armed resistance, the Turks have been fighting Kurds in Turkey for decades. The army and intelligence agencies would likely pick off any new players very quickly.
I'll be in Istanbul for the first two weeks in June, if I don't post after 17JUN19.....you know I got it wrong
