Ok, I do know/appreciate that it is was itself in that context a Neville Chamberlain reference (though he said "for", not "in" ;P), but I think the contemporary Marvel reference was what people would try to make fun of me for (if they didn't know I "walked into it willingly") because Ultron was a bad idea that caused lots of suffering, particularly among people from an Eastern European country that were already experiencing massive strife due to foreign intervention (a la Ukraine, which was what is being discussed here).
