The post is about the hypocrisy of western governments who espouse values of liberty, justice, equality, human rights, etc. but act in contradiction to those values at every turn. Many liberals also profess to hold these values but repeatedly support politicians who use their tax dollars to harm/exploit marginalized communities around the globe.
Obviously this post isn't directed at the people who protest against these things. But the people who protested for Palestine (including Arab Americans) were blamed for losing the election, even though the data does not support this accusation.
