How does the concept of the Overton Window live up to its hype? - sh.itjust.works

I’m unsure if this question comes from what many of you would refer to as skepticism. The inspiration to put pen to paper so-to-speak and ask the question comes from an interesting exchange I witnessed yesterday. Yesterday was the Ides of March, and someone chose the day to ask a question about people acting upon some kind of acknowledgement of the Overton Window due to the political environment we live in today, and someone joked about the irony of asking the question on the Ides of March, which is the day of the year when Julius Caesar was assassinated. Though the conversation then kind of evolved into a conversation after that where people talked about if the Overton Window was a “thing” in ancient times, with there being an understanding among us that the political activity of ancient times didn’t benefit from any kind of acknowledged “moving window”. Anywho, that made me think more vividly of asking this, and it can be seen as a follow-up to a previous question [https://sh.itjust.works/post/55482327] I had asked. As a recap, the Overton Window is the phenomenon where people say there is said to be a window of acceptability on the political spectrum that decides how a community will act in the face of certain societal issues. If the political spectrum was a slit where a lever is stuck into, the Overton Window would be the lever. If you think about it more, in a way that reminds us that politics is meta, historicity, classical ethics, and certain non-governmental aspects of different cultures are enough to go so far as to add a layer of scrutiny to the Overton Window. How would you phrase your answer if you were having a discussion about this and someone mentioned their acknowledgement of the Overton Window was shook by thoughts like this, as one might perceive is happening here?
