Two siblings, in their 40's. One sibling believes the other becomes very trump-like if they disagree and gets personally insulting rather than discussing the actual issue. Other sibling thinks what they say is not insulting and says other sibling is over-reacting. Your opinions will be greatfully received!
Is it insulting to call someone 'cruel' ("I just can't cope with how cruel you are being at the moment")?
YABU - This is definitely an insult
YANBU - Clearly tensions are high, but saying this is not really insulting the other person.
