I think also it is how people say things, yes, there is a terrible war in Ukraine, yes we all know terrible things happen over her and in the world, but we all get on with our lives, we have different threads like style and beauty which posters contribute too, in RL we discuss the weather, life goes on.
I feel the posters who go on to a thread and say not interested, not a 3rd world problem, or get a life, are rude, as they can ignore the post and not comment. Life goes on and we all talk and write about everyday things. I am not perfect, but some posters feel they have a right to be dismissive.
