Left image: It is a social media post by "Bob" showing his support for free speech as a civil right
Right image: It is a list of all the prople "Bob" has blocked on his contacts list
The images are funny since even though someone like "Bob" shows support for free speech as a civil right, he is not ready to deal with the consequences of free speech and chooses to not be spoken to by certain people. He thus blocks people from contacting him on his phone.
