I said quite simply "I don't agree with what you are saying" in a PM. I also asked politely please that politics was not discussed.
And re the whole baby thing...it is my wall and fine, people don't want to see it all the time (I tend to get blocks of 20 mins or so when I post, whilst DF is here playing with DS or DS is asleep), and I do post about him. I could understand annoyance occurring if I posted on someone else's wall about DS, but I don't. I get more people querying after my DS than anything else, so it is clear that the majority of people see it as nothing more than being a proud mum. Anyway, that is not what this is about. Also: by no means are all my posts about DS. Nowhere near. I post about stupid things, things I have seen out and about, whatever is on TV, you know? In any case if someone does not like my talk about DS, they do not have to comment and they can of course hide my posts. PA behaviour is rude, if that indeed is what they were trying to do.
It doesn't really matter to me as to really why these people have decided to do this now, but as I said, others have commented to me, so I don't feel victimised or anything like that.
I am satisfied that what I have done is right for the moment.
