DS1 has been given a badge by DH's mad aunt (MIL Sister) saying 'No to the Monarchy' and she also apparently gave him a 'boring lecture' (DS's words) about how the Monarchy is a waste of money and they take money from poor people like us. DS now thinks this is the truth 
We have heard this all before but have ignored. However this is the first time she has spoken to DS about it. DH said something to her and she replied that she had a duty to tell DS the truth.
I am not saying that DS shouldnt know other peoples opinions and be able to make up his own mind, but as he is a Scout and a pupil at a CofE school it might not be a view he needs to repeat anytime soon.
