This is not meant to be mean-spirited, but rather I present this as humor.
We all love Greta as a child and wish her well.
Unfortunately Greta was coaxed into giving a speech that was way over the top and totally lacked judgement in terms of tone. It seems she is being used as a relief valve for releasing other grownup people’s frothing anger.
It really is just a damn shame she’s been so ill-advised and abused by the adults who surround her. They really ought to know better and be far more responsible.
