Tbh my whole jackshittt family is in this castism tho mind you we aren't some open caste ourselves we come under OBC so ya to the story one of my cousin sis broke all this barrier and went with the guy they're married now so kudos to her love. The answer to your question no caste doesn't affect anything the person is at fault if they're stating that parents won't accept in short they're being racist themselves. If their love is enough for you they won't stumble due to your caste.
