Mainlanders dislike pork eaters?

So a teacher in our coaching who is from Agra told us that if we ever go outside of NE for college or something we should avoid telling the other students or people that we consume pork because they will make you feel outcasted and avoid sharing a table with you even after saying its fine and all to show respect to our culture. So is it true and has anyone experienced it? Asking because i am curious.
