What happens when a single ideology or activity dominates?
It is a very important point and this is what happens when one ideology dominates all discourse and permeates into all realms.
This happened due to religion long time ago, now it happens through over politicization of everything.
So, in ancient Indian literature was imbued with mythologies and religious discourses, now all news and periodicals are imbued with too much of politics.
These things imprint an identity which then takes over everything including our perspective, attitude, thinking, perception or at least frames of reference in our perception etc.
They then go on to dominate our choices and decision making process.
It becomes a vicious circle where the industry provides what the consumers prefers and the consumer prefers what the industry publicizes and we end up with lack of variety, rationality and gulp repetitive non sense ad nausea like bollywood films.
