The ACLU defends the Bill of Rights when it suits their purpose. The occasional lawsuit filed by them on behalf of a right-wing cause is merely a sop thrown to appease it's critics.
The ACLU must assume some of the blame for the epidemic of frivolous lawsuits filed by "victims" of "crimes" against civil liberties. As long as this organization, and the lawyers intrenched in Congress, remained opposed to tort reform, such lawsuits will remain a plague on society.
Having sat through numerous graduation speeches, I can state that many of the graduates speaking have made statements thanking their parents, friends, teachers, and God, for helping them achieve their goals. In the past, no one in the audience even raised an eyebrow.
Not so today. Even red states such as my own are beginning to witness recent immigrants from the left coast or the frozen north raising a ruckus about these statements. They don't get much support from the locals...but the ACLU is front and center lending a helping hand.
They defend our rights when it suits them.
