Agreed. I have NO clue why the OP uses the term 'forced', because that implies that you MUST do them or THERE WILL BE CONSEQUENCES! Nope, just don't do them unless you really really want to.
A better term for this would be automatic quests -- quests which are automatically placed among your list of available quests. It's just like ANY OTHER quest, except that you have a reminder of them placed into your quest log. If they were not added to your quest log, but were equally available, would that be much different?
I agree that radiant quests can be annoying though, not so much that you keep getting them, but that they are so often similar and bland and repetitive. If they never repeated themselves, and they were more diverse, I don't think that people would be complaining about them so much. Just don't do them. It's just like those stupid escort missions you get from the BOS guy. I hate them. They may or may not have been assigned to me (yes, you need to volunteer for them). But that makes no difference to me. I wouldn't care any more for them if they WERE assigned to me automatically. It's not HOW they get into my quest journal that matters to me, it's the nature of the quests themselves.
