Is the fear that your/your spouse's parenting styles/habits will ruin your relationship not a good reason to be CF?

I've seen a lot of reasons here and elsewhere for not wanting kids. But I've never seen anyone mention one of my biggest reasons: conflicting parenting styles. My spouse and I are very compatible together. We occasionally babysit her nephew. These periods have made me realize that while we are perfect together without kids, our parenting styles if we had kids would probably have a huge negative impact on our relationship. This is because we would clash over how we each want to raise our kid. Minor differences between you two that are usually ignored (eating habits, cutlery use, etc.) could become points of conflict because you both want the kid to do it your way (what you consider the right way). Is this a bad/poor reason to be CF?
