What is the most discussed topic in the forum section of ISC so far?

The ISCians discuss almost all topics on earth by raising threads on various topics from time to time subject to overall compliance of the policies and guidelines of the website in general.

However, there are certain evergreen topics on which threads are raised periodically often by newly joined members without actually knowing that the subject matter has already been discussed umpteen times in the past. Sometimes the veterans also repeat the old topics with fresh ideas with updates on the subject matter.

Let us recall as to what has been the most discussed topic in the forum section of ISC so far? Is it reservations in admissions/jobs, gender discrimination, live-in relationships, diabetes or any other such topic?
