You are absolutely correct that India could not do diddly squat about oil prices. Govt has to increases prices.
Now turn the clock back to few years back. The cost electricity went up in states like AP because production costs went up at that time. Who was in opposition at that time. Congress? What did congress do at that time? Organized anti inflation rallies?
When intelligent people asked the same question that you posed above, Congress said it is not their problem, they are in opposition. They will have go on strike.
So what is good congress is also good for BJP. If Congress can fool people, why can't BJP use the people's anger to gather votes? There are enough people who are angry at price rise that BJP will gain from the price rise. There nothing Congress or its supporters can do about.
Keep trying.

Both the housing or mortgage crisis and fuel crisis have largely been driven by greedy abrahamic westerners and arabs. Innocent victims are again the voiceless but optimistic Hindus. Your humiliating abuses against this "xian crook" is well deserved!!
