Hindus are not. Barkas is part of South Hyderabad, which looks more Pakistani than even Lahore. No Hindu ever wins an election there. The locals have multiple voter-ID cards, multiple identities, and on election day, each hop between several polling stations to bring their closet-Paki Muslim leader to power in the legislative assembly or parliament.
It seemed like that before state-bifurcation, because Telangana statehood was born out of a predominantly right-wing Hindu movement. Muslims of Telangana were not just happy with undivided AP, but were protesting against Telanganas. I'll just sketch out some quick history, which will help you understand Telangana.
- Pre-independence Hyderabad province was a Hindu-majority + Muslim-elite princely state (inverse of pre-1947 J&K).
- Muslims oppressed and slaughtered Hindus, collected Jizya, so Hindus assisted Indian Army to "liberate" us (integrate Hyderabad state with India).
- After the conquest of Hyderabad, the freshly liberated Hindus sought retribution from Muslims for the centuries of oppression, and went on a killing spree. Muslim elites fled to Pakiland
- Muslims supported the idea of Andhra Pradesh (Vishalandhra), where in the better educated and better monied Hindus of Andhra would eventually grab power and influence over from Telangana Hindus, giving Muslims protection
- The Telangana statehood movement was essentially those Telangana Hindus seeking to get back their rightful share of political power, which they got in 1949, but was snatched away in 1956 with AP's creation
Today, something has gone horribly wrong.
- KCR is behaving like a wannabe Nizam, breaking peal-necklaces (taxpayers' money) and throwing them at whichever courtesan puts up a good dance (Powerpoint presentation)
- KCR needs Muslim votes for his party to win municipal elections in Hyderabad city.
- Hyderabad civic body (GHMC) wields a lot of political and economic power, it's literally the only source of revenue for KCR, and so he wants to win GHMC by hook or crook
- Minority appeasement has gone way too far. KCR committed the cardinal mistake of calling Nizam (Telangana Hindus' enemy number 01) as "secular."
BJP must take Telangana seriously, because there's a clear opportunity. Congress is a minority-appeasing party, and now even TRS is going that way. TDP is "evil Andhra" party. So the only logical choice left for Telangana Hindus is BJP.
