This is an ancient opinion. People have been complaining about America’s two party system for literal centuries.
I thought this was about Israel doing a genocide because people (especially Israeli people) can’t separate Hamas from Palestine.
But everyone seems to be taking it as a commentary on the two party system despite only one of these things being new to this year?
The ideological signifying here, though, is squarely situated within the language of American politics. All Lives Matter was a reactionary counter to Black Lives Matter, a distinctly American political movement. Similarly, “both sides suck” is something which has been repeated ad nauseam about American politics. As such, the meme suggests itself that it’s about American politics. At least that’s how I’m reading it. If the OP meant it to be about Israel and Palestine, I think they could have framed it better.
Also, the guy in the meme is a… checks notes… Canadian that goes around debating freshmen at American college campuses.
