Thanks on advice and care.Because I care about you and would like to see you actually manage to find one wife, which is why I'm actually the one encouraging you to be open to new ideas!
A hyper-focus on finding a polygamy-minded woman is liable to leave you single - you're searching for a unicorn. Most of us married monogamy-minded women, some of whom have grown in their faith to accept polygamy. I don't care if you find her in a church or a bar or at work. I don't care if you are all traditional about how you go about marrying her ("purity culture" as you put it), or if you just decide the two of you are committed and take her to bed. And I honestly don't care if you end up with one wife or five. I'm just sure that God has someone out there for you, and since your present attitude and actions aren't working to find her, I'm encouraging you to think outside the box. It's possible that she might be just outside your current field of vision, or it's possible that it's you who aren't ready for her and God wants you to change in some way before he reveals her.
So don't just listen to people who you think agree with you - it's enjoyable, but you don't learn much that way. Pay closer attention to those who disagree with you, as that's where you're likely to get new ideas.
It's be way more relevant if I was actually searching for wife. My life is currently too big mess for such activity.
