American society as I've grown up to appreciate it is built on free speech and the free exchange of ideas; the concept that people should be challenged in their views, and be able to think critically to analyze what they hear.

If a group wants to acquire private property and start a club or meeting where they gather to share like-minded ideas and be away from dissent, that is acceptable. The place for "safe spaces" away from intellectual challenge is NOT the square of a university campus.
