This is quite specific and outing so if you know this is me please don't say anything.
For background we have never really been an arguing family and have never had big fallings out or family drama or anything like that so this is a big thing for me.
There is something I just cannot get my head around and has been really really bothering me for sometime now and has come to a head after it coming up again in conversation. Until I can get my head around it I can't speak to my dad which I hate but I can't see myself ever seeing it from his perspective.
He moved away to be closer to his family a long while ago and me and my siblings went and visited a few times and he came to us etc we still maintained a good relationship. We went to visit him before covid and he mentioned something really strange. He mentioned that one of his good friends "John" had been in prison recently (this is a friend of his we were around as young children). He wouldn't say why "John" was in prison but he was saying how it's unfair all his other friends won't now speak to "John" and have stopped being friends with him. My dad also said he had visited him while in prison. I was a bit shocked as I'd known this man since being a child but when he was adamant he wouldn't say why he went to prison we left it and enjoyed the rest of our holiday.
Later on I did some digging and found out that John had been in prison for inappropriate sexual behaviour towards young girls (under 16) and inviting them to do sexual things with him and is now on the sex offenders register. I was disgusted and couldn't believe as a father to girls (and boys) that my dad was a) still associating with this man and b) he was shocked that noone else wanted to associate with him either.
I have a child of my own and just absolutely cannot get my head around hanging out with /defending/visiting a known sex offender. I feel sick. I recently found out that my dad is still associating with this man.
He keeps messaging me wanting to talk and video call for a catch up as it's been a very long time since we've spoken now. I can't put it off forever and cant keep ignoring him. WIBU to go no contact with him over this? Or is there any way I can get past this? Because I can't see any at all. Is my dad just being completely naive/stupid as to why what "John" has done is not something you take lightly? Sorry if I'm overreacting but I'm utterly heartbroken at my relationship with my dad having broken down because I honestly do love him and he's not a bad person. Any help or support/words of advice appreciated!
