Why did a Muslim join BJP, the Hindu nationalist party?

Muslims consider BJP as a Hindu nationalist party and this party and all the members of this party support Hindupeople only. But there are several Muslim people who have joined BJP and still continued joining. Recently former Congress MP from Kerala’s Kannur AP Abdullakutty joined BJP. He was expelled from his party for praising Narendra Modi and thus he is all set to join BJP. Abdullakutty made a Facebook post Praising Modi for following Gandhian values. He said the secret to the PM’s success was that he had adopted Gandhian values. He also hailed the center’s Swachh Bharat Abhiyan (SBA), which envisages cleaning up India’s cities, towns, and rural areas and to eliminate open defecation through the construction of household-owned and community-owned toilets. The Congress party sought an explanation from him but the party expelled him after they found his explanation unsatisfactory. We all know that Kerala is slowly turning into a playground for ISIS. In Kerala, the Muslim majority is higher in comparison to other religions so the chances of Muslim people becoming terrorists are quite high. Even the statistics also show that many Muslims have also joined ISIS. Maybe ISIS gives them a huge amount to join the terrorist or the people initiatively join the group. In Kerala, it can be also seen that BJP never ever won a seat, why? Because the majority is Muslim and Muslim people will not allow a Hindu nationalist party to rule over their state. But with the joining of Abdullakutty in the BJP the chances of winning increased. Abdullakutty might contest the Manjeshwar Assembly seat by-polls as a BJP candidate, which has been necessitated following the demise of IUML MLA, PB Abdul Razak. So that the Muslim vote could be taken in favor of BJP.
