Though it's not entirely wrong...
They shoutet "Şehi.tler ölmez, vatan bölünmez", it means something like"Martyrs never die, our land/nation will not be divided".
This is a frequently used slogan in remembrance for the fallen soldiers in turkey. You might hear this in almost every football match.
It has nothing to do with the terrorist attacks in Paris, but with the bombings and terrorist attacks happening in Turkey(mostly committed by Pkk Terrorists).
It was also a protest against the hypocrisy on how some tragic events get so much attention, while others are totally ignored.
Without a doubt, this was disrespectful...
You are describing the whole thing as if the martyrdom motto has any tangible meaning anymore. These dogs nowadays always shout either "Allah Akbar" or the line about martyrs whenever anti-government people are brutally murdered. These two are used in the same context. It really doesn't have to involve a Turkish soldier being killed by a terrorist. It has become an oxymoron.
Really, I don't want to disrespect you like I did in our latest argument, but I think you have been away for too long from Turkey that you don't have a sound idea about what kind of hellhole it has become. I'd advise you to at least drop the whole terrorist-martyr talk. Today, if you are a Muslim belonging to a sect other than the Sunni or if you are an atheist worst of all, someone who opposes war, an enivorenmental activist, a worker that is a member of an independent union (not one of the government handled ones, which we call a "yellow union"), god forbid a Christian or Jew, an Armenian, somebody who doesn't like Tardogan (as if you absolutely have to); if you don't believe in all the false inflation figures bullshit etc. spewed on your face on TV all day long; if you don't worship asphalt and double-lane highways; if you question instead of blindly accepting just anything; or if you don't like Islam being shoved down children's throats at school starting from primary school;
you are a fucking terrorist. That is that and it won't change.
In that case, even crowds of mobs that are in favor of lynching you will shout out the same lines. And no, you don't hear that in almost all football matches. That is again something you don't seem to know. By the way, you previously claimed that you prefer to question things, not jump to conclusions. But the fact that you are explicitly calling victims of Suruç and Ankara bombings terrorists tells me otherwise.
