Possible answer: There are several reasons behind the statement made by CPI's D. Raja regarding the coming together of secular parties to defeat BJP:

• The rising influence of BJP, its Hindu nationalist ideology, and the policies of its government have led to concerns among many parties and groups that the secular and pluralist character of India's democracy is under threat.
• The increasing polarization and communal tension in the society, fueled by the BJP's aggressive campaign to create a majoritarian hegemony and suppress dissent, have created a sense of urgency among these parties to unite against the BJP.
• The failure of the Congress, the traditional rival of the BJP, to challenge the latter effectively and to offer a credible alternative vision has made it less attractive as a partner for other parties.
• The emergence of regional parties, especially in states where BJP has faced strong opposition such as West Bengal, Tamil Nadu, Kerala, and Andhra Pradesh, has given a new impetus to the idea of a federal front that would promote regional autonomy, diversity, and social justice.

The ultimate goals of these secular parties could be:

• To prevent the BJP from winning the 2019 Lok Sabha elections and to limit its power and influence at the national and state levels.
• To promote a more inclusive, tolerant, and democratic India that respects the rights and dignity of all citizens, regardless of their religion, caste, gender, or ethnicity.
• To challenge the neoliberal economic policies of the BJP and to demand more redistributive and welfare-oriented policies that address the needs of the marginalized and vulnerable sections of the society.
• To foster a pluralistic and cooperative political culture that encourages dialogue, compromise, and consensus-building, rather than confrontation, polarization, and intimidation.

Overall, the coming together of secular parties against BJP represents both a response to the threat posed by the latter to the democratic and pluralist fabric of India's society and a vision of a more equitable, just, and diverse India.
