This post was ridiculous. Many liberal policies have had clear effects, such as civil rights legislation, and Jimmy Carter creating DECADES-LASTING PEACE IN THE MIDDLE EAST BETWEEN ISRAEL AND NEIGHBORING COUNTRIES after virtually continuous war.
This is not about actual liberal policies. This is a humorous post about the social board game “Secret Hitler”, in which players can enact liberal and fascist policies as part of the game mechanics. Like, the conflation between the game world and the real world is part of the joke, but should not be taken as a literal statement.
If it shouldn’t be compared to reality, than why are the other posts not also voted down? They are both about how the real world is comparable to the game. Aiyen even has “Sadly this one is likely true irl” when explaining one of the points.
There is a difference between engaging with an allusion, and accusing the author of making a claim he did not make. None of the other comments took what the author said at face value in the way your OP seems to do. (I.e. the author definitely does not believe that no liberal policy ever had any effect)
