I am totally perplexed as to why I should have a 'forced' visit to Gransnet- how could anyone force me? 
Of course I can understand how you feel about grandchildren.
I am only stating one fact- not a pleasant one- but a fact. You can't have a good relationship with grandchildren if you are estranged from the parent.
A court order for your 'rights' won't give it. e.g. If I thought my parents were so toxic that I cut contact, and it was generally so poor that we couldn't resolve it, even with mediation, then a court order wouldn't give a good relationship. For example it would have to be at my house, under my supervision, or at a centre with a neutral third party supervising. There would be no unsupervised visits, trips out, school plays etc. and it would be the bare minimum.
There is NO possibility of me ever doing this, I hasten to add. I am just trying to point out that giving grandparents their 'rights' won't make for a good relationship.
I firmly believe that children benefit from grandparents, that some get cut off through no fault of their own. You appear to be shooting the messenger because you don't like the message!
I wish someone could explain how you hope to legislate to give grandparents rights if the parent is forced to comply. Or rather how you hope to get a normal, loving, involved relationship from it.
