I think in quilting there's something for everyone, and I just don't think mystery quilts are your "thing". No big deal. Just accept that it's not what you prefer to do, and don't participate. Life is short. Spend it doing what you enjoy, and don't beat yourself up over the fact that you don't enjoy it. No matter what you're considering, there's always someone who doesn't like to do that particular thing.
On the other hand, it is true that sometimes we just have to try something we don't want to do, because that's how we learn and grow. You may be pleasantly surprised if you can let go and try it. But if you've already tried mystery quilts and already know it's just not for you, let it go, don't participate, and move on to what you do enjoy, guilt free.
