Whenever the word “tolerance” makes its appearance in a screed like this, you can be certain of its political bent. Always.
There is to my knowledge no professional group which does less for its members than the ALA. It is 100% a left wing advocacy group 0% librarians advocacy group.
The organization lives to bash conservatives and Christians.
When a group of Minnesota librarians complained about sexual harassment by public library internet porn surfers the ALA took the side of the porn addicts.
I know of no position taken by the ACLU which the ALA does not support including the legalization of child porn.
As bad as the National Education Association is for education it has been good for many teachers. You can argue in its defense that at least it aggressively promotes the interests of its members. Teachers in many locations owe their financial well being and out sized pensions to the single minded aggressiveness of the NEA.
On the other hand thanks to ALA focus on politics not the welfare of its members, Librarian’s are at the absolute bottom of the wage scale for professionals. It is hard to find a field in which people with Masters degrees routinely make less than 40k a year.
