Who cares dude? There are thousands of Mosques across India that are built on top of Hindu Temples. Hell, even your most holy temple---Kashi---has Mosque on its grounds.
What can you do? Nothing much. It took poor Hindus more than a
100 years to get one temple rebuilt, and that too---you had to give Muslims
DOUBLE the land for a grand new Mosque (Babri Masjid was in 2.5 Acres, Supreme Court ordered Indian govt to give 5 acres for rebuilding of Babri).
Thing is, no matter how hard you try---you can not undo the defeats and humiliations of the past. Dharma was eradicated from Indonesia, Malaysia, Pakistan, Sindh, Kashmir, Bangladesh, and Afghanistan etc. Most of these lands are 90%+ Islamic today while the only remaining Hindu-majority area is less than 80% Hindu. Nepal had Hindu monarchy and it was overthrown by communists and you couldn't even save it (While Islamic Republic of Pakistan fought Soviet Union and brought 4,000,000 sq. km of land area under the fold of Islam in Central Asia).
I know these things are hurtful. If I was Hindu, I'd be super aggravated at the injustice of history as well. But it is what it is---you can not undo the history. Global Islam is way, way, way more powerful than anything hindus have been able to muster in their entire history. You can't take back lost lands. The best for you is to accept reality, live peacefully in your only remaining secular Republic, and stop obsessing over "secularism" and "Mullah" or "Love Jihad" day in and day out.
Some of the oldest, most important states of remaining Hindu-land (India) like Kerala, Assam, and Bengal are on their way to be 30%-40% Islamic in coming years. Can you stop it? No, you can't. But these states won't be Muslim-majority ever unlike the Hindu right wing propaganda says. My question, why do propaganda to hurt your own citizens? It won't get you anywhere. Just accept your fate and work to build current india into something less miserable than it is now (Ranked literally at the bottom of world happiness index).
Let go of anti-Muslim hate and inferiority-complex, and leave in peace and find happiness. Simple
