"loving a mono is fraught with difficulties because they just do not understand us.
Bless them, they have to take on trust that we truly love them and override all their feelings by acts of willpower."
I guess you have to be mono to be offended. The way this is written makes it sound like we are incapable of understanding polys. "Bless them" is something generally said to children or someone not quite with it. I agree that some monos never really understand their poly partner but that is certainly not true of all of us.
Personally if I couldn't understand poly and had to spend my whole life willing myself to trust that I'm loved I wouldn't be in this relationship.
