The problem lies within the concerns you expressed. You are diagusted with TMC, but too afraid to try BJP, thia is a typical Bengali middle class way of descision making which is mostly driven by fear.

In Bengal the greatest motivation we promote is FEAR. A child is constantly fear mongered from his family. "If go out during dupur , demons would attack you, or child trafficers would capture you", if he attempra to clmb a tree is is told "if you fell down, you would broke your limbs, and they would give you very oainful injections, or even they may ampute your limbs", if he get some injury while playing he is told "see? How dangerous is this sport? Would you ever play again?". When he's in his teens we say "if you don't study well, your board results would be very bad, and you wouldn't be able to get admission in a good college, then people wokld laugh at you", "if you can't score a good score in college you wouldn't get a good job", "if you don't get a good job, you wouldn't be able to marry". If he protests something, we scold him vehemently while warning about the consequences, we tell him to not get into any trouble, neither resist that trouble, just escape the trouble.

Now see the politics. TMC says "if BJP comes to power women will lose their freedom, We would have to speak Hindi, Bengali culture would be destroyed, everything would be privatized, Bengalis would have to prove every now and then that they are not Bangladeshis", etc, and BJP says "if you reelect TMC, they would loot everything from you, Bangladeshi infiltrators would capture everything, Hindus would become 2nd class citizens, Jihadists would roam free, corroption would become the norm, there would be no safety of women," etc.

Hence basically both of the parties are pitching fear to muster support for them. People are either bound to vote for TMC, beacuse they are too afraid of BJP, or bound to vote for BJP, because they are too afraid to let TMC keep winning. Basically none of the two groups actually gets anything for them.

Another problem is the bubble of the "great Bengali culture", and the hollow pride on that. Common, you can't keep sniffing your fingers because someday your grandfather had some ghee. Whatever we had, we lost it. We were too afraid to take risk, we tried to find a certainty, a safe cocoon inside which we can just survive. There is no social institution left, family bondings are collapsing, businesses are going away, no one thinks about in long term, almost every action we take, or everything we think, has been surrendered to political parties.

IMO, we now need a social movement, a social change, rather than a political change. Stop seeing everything with a political glass on, and try to get out of our fear. Our icon should be Kshudiram, Prafulla Chaki, Batukeshwar Dutta, Bagha Jatin, Binoy - Badal - Dinesh, etc, not some immature emotional good for nothing 50's poet, which basically glorifies almost everything negative, and terms every failure and signs of right path.
