What you said about Turkey applies to India as well - India is not a "Hindu country", it is also a secular democratic republic.
And by the way, our Muslim population is about three times that of Turkey's. We have more Muslims than any country in the Middle east. By a long way.
(I am not condoning his posts, just pointing out the fact that India is a secular republic, in the same way you said Turkey is.)
On topic, RIP to the victims, and I hope Turkey brings the perpetrators to justice. Best wishes.
