If somebody don’t like you for whatever reason, then it’s better to pursue someone who WILL like and accept you. But people can’t be stopped from having opinions, regardless of how others might view them. We have opinions about inanimate things like vehicles and movies and books and clothes. But it’s considered a bigger deal when one has an opinion about a human being. Human nature. It would be more snobby to openly voice your disdain for the prospective rishta to his or her face. However, if one politely refuses the rishta and wishes them well, i don’t think it’s really snobby. I know that nobody is perfect but it would be fair to neither party to be commit when either side is not wholeheartedly interested.
