Of course all political parties are disgusting in liberal democracies but there are some that just are insane.
In Mexico it has to be PAN, they’re your usual latin american conservative party. Elitists, very catholic, racists, malinchistas ( they hate mexico and its culture ). Right now they’re going insane because a former secretary of national security was declared guilty off collaborating with drug cartels in a US jury ( they idolize the US so this is funny af )
All of them except Communist Party of Serbia, every other one is either pure bourgeoisie scum, nationalists, monarchists or full on fascist. Same applies to Bosnia, Montenegro and Macedonia.
