I do not know what is wrong with someone stating that they are more concerned over Jewish tragedies.
I view other Jewish people as extended family and I think it is natural for someone to feel more concern over members of their family then other people.
Of course this does not mean that my heart does not go out to thos eparents suffering from this horror right now, however I do not view non-jewish people in the same way as I view Jewish people.
Which I am sure is the same way vice-versa.
Ex. Several years back during the Second Intifada I was in the car with a group of people in the the US.
We got word there had been a bombing in a certain part of Israel.
I asked urgently if it was in the Chareidi section of that city.
Someone else blew up at me.
How can you even ask that, and irreligous jews mmean nothing to you.
I kept quiet rather then explain I have a vast number of reletives throughout Isreal.
However the person who blew up at me came to understand it on his own.
The next day I recieved word my first cousin was in the blast and her child was killed instantly R’L and she, and her husband sustained severe injuries (that have left their mark till today).
My point is that we are naturally more concerned with our own then with others.
Of course if someone would view themselves as an equal member of the non-jewish community this would not apply.
