Most people do not hate marriage, just the person they are with. Remarriage can lead to a satisfying relationship.
The problem is not religion, but false, cultic, destructive religion. We are created for relationship with God and will be restless and lost until we find Him. Just because someone had a bad experience with a clueless doctor is not a reason to never seek medical help again from someone else.
Many former cultists now have the love, joy, peace, power of God found in Christ alone that they never knew in manmade religion. The issue is if there is a God and true faith/beliefs. If there is, it will satisfy and set free and be the source of abundant and eternal life. If it is an illusion, one religion may be as good as the next.
The sad danger is to think that a negative experience means it is not possible to have a positive one. I can have a bad work experience with a bad employer, but that is not a reason to never pursue a good work experience with a good employer.
There is a difference between a reason and an excuse. Those who leave cults leave to a vacuum and can end up no better or worse off. Joining another false group is worthless. Finding a true relationship with God means everything. We are all in the same boat as condemned sinners. We need the gospel, the power of God, which is centered on a person, not an organization.
