If people were saying that the matches of India vs Pakistan shouldn't be even played under ICC tournaments and regulations I think they have just lost their mind and they are just some lifeless beings who have nothing better to do than spread hate all over the world.
You may think that these sort of discussions are initiated only among fringe groups with no parliament representations. But that is not true. When India was facing Pakistan during the T20 World Cup in the UAE, one of the major regional parties (Shiv Sena) actually asked the government and the BCCI to pull out of the tournament, so that India doesn't need to play against Pakistan. And incidentally this is the same political party which once dug up the cricket pitch in order to prevent a India vs Pakistan test match.
