So, start your own demonstration. Wave the Turkish flag, have signs that read in Kurdish and demand that Kurdish should be an institutional language ( not official state language, but instutitonal, there is a difference). Demand that Kurds and Turks are treated equally. Give Kurds a reason to love the flag. If for instance Turks had risen up after 1980 coup. If Turks had risen up and had said that Kurds should have their language rights and should have the right to gather and do cultural activities etc. then there would be no need for PKK.
But now you want me to declare that PKK is a terrorist organisation. How do you want me to do that? When I was a kid, the only people that stood up for Kurdish rights were PKK. When I turned on Turkish tv, I would see ALL Turkish partys claiming things such as '' Kurds do not exist'' , '' Kurdish is not a language'' , you know the rest of the story. Then PKK came and suddenly Kurds were aknowledged, Kurdish was a free language to use etc.
But again, if it had been Turks, and not PKK, that had stood up for Kurdish rights, there would be no need for PKK. But you fail to realise this. Instead, you want to force me to say that the ones who preserved my identity as a Kurd and defended it with their lives are terrorists. It would actually equal me , forcing you to say Ataturk is a terrorist right after the liberation of Turkey in and the preservation of the Turkish borders and language in 1923.
