Now repeat after me ... "its for the children".
This is the problem with grown adults using a child to push a cause. As soon as people start disagreeing with the child, said adults start hiding behind the child shouting "why are they attacking the child, they must be evil".
I acknowledge that some people go to far in their personal criticism of Greta herself. But this was to be entirely expected, and its something her parents should have shielded her from. It's pathetic parenting, and bizarre how blind some people are to this. You really think pushing a child forward is a serious way to talk about climate change? The whole issue as become a farce, well done.
This is only your view, but could also be that this child has moved forward on her own (though impossible to know how much others are having an influence on her now; so it goes in to being "unknown"); it is only our opinion on what could be the issue here, but regardless I still stay with my original condemnation on the verbal/written attacks on this girl in general, but I would like to think that such attacks from more influential individuals will be more restrained.
