From what I can gauge, many of the current active forum participants are very much keen on discussions related to politics. With the ongoing national elections, it is not surprising, then, to see them in animated interactions on that topic! In fact, it is a healthy sign of our country's democracy as a whole that there are citizens who are expressing their opinions freely on various aspects of politics.
On the other side of the spectrum is the problem that political discussions may be curbing greater forum participation from other members who are not really keen on political-related topics at all. It is thus, as Saji implied, creating the impression of a social media platform exclusively for political debates. Are such debates keeping away members is a serious point to consider.
I would also like to point out that the presence of editors in forum discussions has drastically dwindled. Over the years, those members who took on the role of editors have spent fewer hours in the forum. The responsibilities of editing, as well as the eagerness to contribute, seems to have drastically limited their forum participation. I had also a couple of times expressed a willingness to make an effort to be more active in the forum (which I was for many years), but somehow that has not materialized. Perhaps if I and other editors also got back into the groove and come up with fresh topics as also interact wholeheartedly in forum discussions it would help to take away the focus from political-related topics.
