My private forums, why?

I'd for sure have a private forums for my friends only. And I don't understand how can someone be my friend without having the same political opinion. Also, what is private without a secure computer and a secure server? Because I doubt I'll have this someday. If it's hard to be secure for people of all class, on my case it's even hard; how can I have a password for example? So if the day come, it'll be, and we could grow a lot.

Also, I could try to have a forum with some other people that are not like me. This is going to be try maybe but I doubt this could work. We'll see later and for now, I'm stuck on Reddit, God force me and I would not be surprise if he force them.
