If your town library wants to get federal dollars, they have to do as the feds say. Gotta dance with the date who brought you.
Wanna be free of federal dictates in the library (and elsewhere), then shun the federal dollars.
And can a community that does so receive a rebate of the federal dollars its members put in but are not taking back?
Today's situation is alalagous to a mugger who takes $100 from someone but tells that person he can have $95 of it back if he does something the mugger wants. Sure the victim is "free" to refuse the mugger's demands, but only by forfeiting $95 of his own money which he should be under no obligation to part with.
You're lost. Federal dictates are for filters. The ACLU is opposed to filters regardless of where the funds come from. I am in favor of localities determining what appears on the internet in the library we paid to have built. My take is that you support the ACLU in their position. Correct me if I'm wrong.
