I do not know much about Turkey's internal politics but let me say AFAIK .
If Erdogan was the main leader to remove the ban on Hijab so such a leader must be fully supported by Sincere Muslims and i did see some videos in which Erdogan came out of the masjid after Fajar salah and met mainly groups of women wearing Hijab and were waiting to meet him. though some said it was just a Propaganda but my view is EVEN if it was a Propaganda but it was the right thing (propaganda) for a sincere Muslim ruler to do that he Prayed Fajar salah with jamat
SO THAT OTHERS FOLLOW HIM . About some claims that he is a tyrant , If he could apply Islam in a Muslim Majority country were Hijab was detested Naturally those who supported The Hijab Ban will consequently call him a Tyrant since he has forced Hijab on them ..
So such Islam applying Tyrants are welcome provided they do not behave like ISIS going against the Noble Quran & hadith and killing its dhimmis & Muslims alike in the name of islam. The Need of the hour for the Muslim Ummah is such Leaders like Erdogan though the method to Power was not 100 % Islamic but still its better than the worst like those leaders who supported shaitan and a Hijab ban & filthy westernization.
