This is kind of funny. The Deseret Spectacle still believes that the ACLU goal is to defend civil liberties. The ACLU's goal is to define civil rights within a secular progressive agenda. Libertarians and ACLU goals sometimes mesh up as the Libertarian Party notes, and sometimes diverges.
An interview on Reason finds that the ACLU is for gun control, and only interested in the parts or interpretations of the Constitution that align with its agenda. The ACLU often uses groups that it disagrees with when it argues cases. They have a long history of agreeing with groups that are a tad scary.
The fact that a civil rights group has an agenda isn't really bad; so long as the group is not taken as the group that defines civil rights. There are other civil rights organizations such as the Rutherford Institute that supports the rights of the people outside the ACLU agenda.
Anyway, The Deseret Spectacle thinks it amusing that the NRA is diminishing now that gun control is not a major agenda of the Democratic Party. I am not a fan at all of the NRA (I don't like to associate with unpopular groups). However, the fact that the group is diminishing shows that it NRA is an authentic organization that was interested in defending gun owner's rights and not a hidden agenda. The cartoon shows the NRA as just a bunch of thugs. That is just media bias.
It is a little bit strange that the cartoon shows the NRA as big thugs attacking the poor little Democratic donkey, when it seems to me that gun control legislation was actually the case of a powerful political organization trying to take away the rights of gun owners.
