I'm a Christian and can relate to this. I came to faith in my thirties. It didn't happen in a vacuum, and was absolutely not something I saw coming. If someone had told me I'd become a Born Again Christian I never would have believed them. I don't come from that kind of background and it was as much a shock for me as it was for other people.
But I can't deny that I felt God's hand over my life and there were experiences and circumstances which led me down this path. I've co pletely changed as a person, for the better. I thought I was a moral person before, but something within me changed from the inside out.
This transformation was beautiful and sometimes explaining what happened and how I came to this conclusion feels like I've poured my heart out and invested emotional energy in retelling profound experience. People respond with scoffing comments with the usual 'sky daddy' tropes and honestly sometimes it leaves me feeling like I've shown someone my prize collection of jewels and they laughed at it.
My husband is an atheist and I'm not scared of an intellectual debate or philosophical differences at all. Mumsnet just tends to spout out clichés and generalisations about people of faith which are so sweeping and ill informed, that sometimes I don't have the emotional energy to engage in it. We are seen as one big oppressed, brainwashed, unthinking, uneducated, thick monolith when we are a vast array of personalities, backgrounds, upbringing, cultures, education levels, professions and unique experiences, and we all arrived at the same conclusion.
Sometimes, people often don't want to hear. They don't want to know your story. They only want to put believers through the hoops to make fun of them.
