judicial activism from the "conservative" wing of SCOTUS

In the latest national security ruling from the Supreme Court, the majority has

Upheld a federal law that bars "material support" to foreign terrorist organizations, rejecting a free speech challenge from humanitarian aid groups. The court ruled 6-3 that the government may prohibit all forms of aid to designated terrorist groups, even if the support consists of training and advice about entirely peaceful and legal activities.

NPR has reported that the majority argued [agreed with] two points [concerning the peaceful, legal support given to terrorist organizations] :

• It may ostracize allies.
• It may give terrorist organizations an "air of legitimacy"

These are not legal arguments. Just call balls and strikes, John.
