I have been rooting for India too. I didn’t intend to - started watching as a neutral but just drifted into backing the side not called England with three lions on their front, and all the other symbols of Engerland that come with the package.
It may say England & Wales Cricket Board in the small print on the letterhead, and a few Welsh players may get a look in (with the Irish, Zimbabweans and South Africans) but the team is still England. I never felt I had my own national cricket team to support - it is an emotional not rational response - but the way it is.
I always support West Indies when they play but have had as often spot for India since going to watch them against England in a one day match at Headingly about 5 years ago. Their team were much more likeable than England’s and that was even more true of the fans.
National identity and sport is a funny old game!
