Well, this depends on your situation. If you have access to a Novus Ordo Mass where there is a danger to your faith due to heretical preaching or unworthy elements within the Mass itself, then you have the right not to attend and to go only to the Traditional Latin Mass. If you have grown up with the Traditional Latin Mass, in that case, you can choose to attend only that Mass. However, if there is a worthy Novus Ordo Mass, though such instances are rare in the current state of the Church, then it may be acceptable. So, I would say it depends on your specific situation.
