Just because the current theory doesn't understand that India was located at the antipode of the Chicxulub impact doesn't mean that it is right. The other three large impacts of the past one hundred million years showed contemporaneous mantle plume activity at the energy antipode (located close to the physical antipode). There is plenty of evidence indicating that the Chicxulub impact followed suit.

But Ben... didn't you see what the blogger wrote?
Be careful here. The impact did not initiate Deccan volcanism. That was caused by India rifting away from Madagascar (88 mya) and Seychelles (66 mya). The rifting and an unusually hot mantle underneath resulted in copious amounts of melt being generated in the mantle which found its way to the surface via the great tensional cracks formed when continents separate

Your theory has already been refuted, seen by many peers, and accepted. To continue with linking the two events by applying causation to the bolide is folly.
I'm sorry, but you're beating, not a dead horse, but a non-existent one.

No. They still have more work to do. But they are getting closer!

Ahhh, now there we go! That makes more sense! I don't believe much in coincidences and it always seemed odd these two things happening nearly at once in a geological context. However, folks kept saying they didn't match up perfectly in chronology which stretched credulity for me. However, advocates for a causative relationship lacked proof.... and the time correlation has been better constrained and a mechanism offered. Nicely done!
