My parent in their 80's (not suffering from dementia) constantly instigates fights either with myself or others. The subject of the fights usually isn't personal but eventually escalates to that point. My parent watches nothing but 24-hour news shows or network talk shows that are similar. The instigating starts by bringing up something political or some socially inflammatory piece they've just seen or heard. Or they will make something up claiming that they saw or heard for the sake of getting the fighting started. Even when they're warned in advance if we're going to a social outing or have guests not to start anything political or inflammatory and even go far as to state what things they will not try to pick a fight on, it's no use. They manage to do it. We cannot have family gatherings or friends over because the visit or events always gets turned into a soapbox/forum for my parent to get into it about politics or some socially inflammatory subject matter. At this point we don't entertain friends and family at home anymore because when my parent has a bigger audience will work double hard to instigate the fighting and yelling. Any suggestions on how to stop the instigating before it starts? I would really appreciate any advice.
