Me: do you think they're justified, both Nparents, in banning me from communicating with you (FM uncle)?

The reply:

They were still and always will be your parents, and I the doting uncle..
But some, seem threatened by this.
I have done no harm to either of your parents. In fact your Mom had resumed communicating with me from March last year, ever since Nana came to live with me.
Perhaps they have offered their reasons to you, for this banning.

My other sisters have adult kids with whom I communicate almost daily.

Seems your parents
became unhappy when I did not inform them that you were communicating with me, over element.
Naturally, I wanted to assist you as best as possible by even inviting you to come to brazil.
I'm flummoxed really with their attitude.

Now that you back home, I hope that all the necessary steps are taken to get your place back.

Mom is no longer communicating with me, in fact she has attempted to vilify me with the rest of my family, here in brazil... they have no desire to heed her wishes to end our strong relationship

Some analysis; notice how in his whole reply, he sorta addressed my original question, but he doesn't directly and sorta beats around the bush. He throws in a 'They were still and always will be your parents'. This, 'now that you're back home, your [...] safe', couldn't be less true, and they should know that based on my previous complaints.
