Are there ANY spaces on the internet where people are NOT secretive about incest?

I find it more confusing than anything, like, you’re here in an online forum of incest people discussing it, but at the same time talking about how bad it is for your mental health or how you would be so ashamed to tell your family. If you’re so ashamed, WHY are you here? Why do people act so ashamed but still look into this topic? I don’t understand.
