Meme I don't understand

Can someone explain to me the thing where you take a politician's face and make it into the Joker? Comme ça:



Or:



I feel like this is an incomprehensible political statement. I mean, the Joker is clearly Chaotic Evil while most politicians are Lawful Evil (like Nixon said, if the president does it, it's not a crime) and also, the Joker is, well. Cool. Also, probably unconcerned with politics, and certainly not a socialist. Does this make the person holding the sign Batman? Are we all aware of Batman's class privilege and problematic politics?

It makes less sense than Guy Fawkes as an icon of 21st century rebelliousness. At least there's a paper trail there.

Also

I'm still uncomfortable with the concepts and rhetoric that make up Mad Pride.
