Does it make people feel morally superior or something to go on about the "western media" and how "that country has it worse" all the time ? Personally I think it makes you arrogant and self righteous but eh.
I mean, what do you expect really ? For people to grieve constantly ? For tragedies happening in war-torn countries to make front page everywhere ? That would be quite literally every day, you'd get tired too. And it doesn't have anything to do with valuing their lives less, it's just that after a certain point it stops being news and it starts being "normal", as sad as that is. Mass shootings in the US are treated the same here btw, so the argument about islamophobia or the big bad western media...
The biggest terrorist act France has seen since WW2 in the most visited city on Earth though ? Yeah I'd say that's a little exceptional, and it is more likely to draw emotional reactions from the western world.
Should other countries have done a minute of silence ? Maybe, that's a fair question (though it's something that should be asked of Turkey first don't you think). So Turkey's response to not being shown solidarity is to disrespect the deaths that happened in France ? Oh yeah, that sure will show us westerners how worthy you are of respect and solidarity. You could have had a banner or a tifo or whatever, hell, the organizations in charge could have asked for these victims to be mentionned as well, honor your deads without disrespecting others, booing is childish at best.
