I come here to read interesting technology news, and most of the Doge stories are not interesting technology news. It would suck if HN were full of boring stuff that I can read elsewhere.
I do care a lot about the current situation, and I keep up to date by reading all the other sources that cover politics and the economy. I flag most politics articles because they lower the quality of HN.
If something is either very novel or very interesting it should definitely make it to the front page. But most stuff that gets flagged is getting the right treatment.
However, the one you posted does look kind of interesting. It probably got flagged by people who are even more sick of politics polluting HN and are flagging reflexively.
