It can be valid, it surely doesn’t apply to Gaza.
We are “all” guilty because we knowingly pollute, for example, and that kills people. And we buy products and that finance Israel bombs. And we fight for survival and strangle our jailer that just landed that job to feed his family and never got quality education to choose a different career.
I am more of the idea that there are no truly guilty in a strict sense. We as a society share the responsibility to handle the now extended knowledge we have and we are basically not even trying.
You hear this a lot, but then you and look at “the times” and find arguments in favor of cultural integration dating back thousand of years.
It is true that people are the products of their time, but those times are not as radically distant moral wise as it is usually assumed.
