Yes, perhaps that was worded somewhat poorly. The ACLU certainly does lobby for political change as well! They did not historically, however, take into consideration the degree to which one's political agenda aligned with theirs when deciding whether to render aid in the defense of (legally guaranteed!) civil liberties.

It's also worth noting that the meaning of the word "political" is overloaded here. I did not use it in the same sense that you did - I hope that doesn't escape your notice. (Still though, a potentially ambiguous wording is nonetheless a shortcoming. It's on me to ensure that my communications are as clear as possible.)
