You don't have to agree with a ruling to understand a ruling. In this case, understanding Roe vs Wade means understanding that it was argued using the 14th Amendment. Whether or not you agree with Roe vs Wade is rather irrelevant.
It's very relevant; the current public abortion debate is a direct consequence of the fact that the supreme court doesn't agree with the ruling. You don't have to agree with it to understand it, nor to understand that it is incorrect.
When this future ruling comes down, I highly doubt you'll be citing it as justification for it's own existence and saying that disagreement is irrelevant. Those that are happy with it won't be either, they'll justify it by saying it is the correct one, in their opinion. Whether one agrees or not is at the core of the conversation.
