OK, absent context you make a valid point. One that I agree with from the standpoint of a private sector tax paying business.
Now lets add the context of the ACLU being an entity that is at least in part funded by tax dollars gained from suing public infrastructure and collecting lawyers fees for doing so.
Lets add the context that the ACLU is supposedly doing much of this suing under the pretext of privay rights and the ability to speak your mind freely.
I ask you this, how does an entity in this context retain its credability (barf) on the issue of supporting free speech for all when they restrain their own people from excercising that very speech?
Do as I say not as I do? Sure looks that way to me!
