Saw this in hexbear memes yesterday. To me it reads as a satire of the holier than thou attitudes I see around here. But it also had no downvotes and nobody was challenging it, so I wonder if it reads differently to you, and how if so.
I tried asking the OP but I was told not to expect discussion in the memes community
vague or confusing memes end up getting upvoted on here all the time. there's usually several different interpretations.
In this case though, I think its pretty clear that neither of these people depicted have any power to decide which track the trolley goes down, they're... physically disconnected. It reads to me as making fun of electoralism in general. Liberals fit just as easily into the "I will achieve greatness (slightly better conditions at home) by allowing the death of others (genocide abroad)" role as conservatives do, if not more.
What it lacks is depicting an alternative that actually works to stop the trolley, but it still makes the point that electoralism is fuckin pointless
edit: I see the OP popped into the thread further down. It makes more sense if understood as a leftist response to the unedited version where the lever actually does anything.
