I have found 623 to be polite and gentle in his attitude and his posts. Robbie I know nothing about at all, but if he can make 623 feel this way then perhaps there is need for it. I don't know so I am minding my own business.
I don't think anyone has the right to try and force people to be friends, and if 623 feels justified in his attitude to Robbie then I would never try to tell him he has no right to his feelings.
Since 623 seems to be reserving his anger for Robbie alone it doesn't effect the rest of the forum. I think it is a shame that anyone would come here and deliberately try to spoil it for other people, especially someone who seems as nice as 623. But he seems well able to cope with anything Robbie throws at him, and he is being quite polite most of the time too, so I have no problem at all with him sticking up for himself.
I am sure if they want to be friends at some point in the future they will sort it out for themselves.
Until then I will post as usual and unless 623 asks for support I am keeping out of it.
