If you were engaged to someone your parents hated would you go through with the wedding?

So you have been dating this person for a few years. You love him/her but your parents hate him/her. Now your engaged and your parents have even more hatred towards your fiance. Neither parent wants to be at the wedding. What do you do? Do you go ahead with the wedding despite your parents? Or do you hold off the wedding until you can calm your parents down and explain things to them?
