I don't think anyone would object to that? I think we all agree that Hamas killing a baby and an unborn baby was a terrible, terrible thing. There doesn't seem to be as much condemnation for the babies that as US Drs who have been in Gaza say are dying everyday from malnutrion or the children and toddlers that are being shot in the head every day by the IDF. I think that is what caused anonymous to speak out really, if there was as much condemnation of the IDF then the US wouldn't be supplying them with arms and giving standing ovations to Netanyahu.
The only reason groups like anonymous are making a stand is because those in power who should are sitting back and doing nothing. It doesn't really work the other way around though, the US isn't funding Hamas or giving them standing ovations for killing children, Hamas are rightly being condemned so there isn't the impetus there.
