Kingston, like you just said it is an internal affair and I/we don't think you should be sniffing around telling us what to do. The problem we have is complicated and somehow allows this unusual and maybe seemingly insultive tone to be used.
Long story short, noone is mad/ unrespectful to anyone and we can handle these problems on our own, thanks for the good suggestions, though.
Also... Noone is forcing anyone to be in the family, what is more, if the person in the centre of the event has tried scamming one of the family members and clearly violated the main principles of being a good participant in the Colombo family business.
