This is such an important point, and I wish it were more widely spoken about. As a daily NYT reader, I noticed a profound shift in the early days of the current admin. I might be off on the timing, curious to know what other daily NYT readers have to say. It's an incredibly effective technique given the relative subtlety, and in my experience it seems to exhaust the mental resources of the critical reader.
You're very very off on the timing: the first year of the genocide (and the majority of the official casualties) was under the previous administration. The bias on Gaza was observed across the board from the start (and arguably for the last 70 years).
