I really hate it when they bring in something and make it about religion. There is no need to do that at all. Now I know that there are a lot of controversies going on with the ICC and the way they handle things. A lot of people do say that India is always being favored by the ICC. But the thing is people are not going to respect your team. If you do not respect it yourself. And respect will always come when you start playing well.
As you said, Virat Kohli was out of form for quite a while. But I dont think that former cricketers or even the media of India said anything bad about Virat Kohli. They supported their flair when he needed them the most.
Here we have to understand few things specially culture of subcontinent where religion is key factor for last few decades because of political influence so if someone doing things like this even never been good or liked but still happening because they have no other positive way to give their personal thoughts.
So, they include things like these which create more mess up even many crimes are going happen just in these religion circumstances but no one can do anything positive for change as education and personal sentiments are having big impact on this all and remember one thing creating of Pakistan is also just based on religion so this all is part of the life and nothing can change in near future.
