The obvious response is that Gaza is a very densely populated place, of course there's civilians near any given location, that's not a conspiracy by Hamas. But are there any other talking points I should hit?
(I'm not really a lib in rehab, but this seems like the comm for getting talking points straight)
Hamas are prisoners among prisoners stuck in an open air prison. There is nowhere for them to exist that doesn't result in them being surrounded by civilians.
Israel moves settlers onto stolen land literally within hours of taking it so that anyone fighting to take it back has to go through the settlers. They literally use civilians to shield their advances.
