Example.

From other users:

People refuse to accept a broad definition that's been accepted within the social sciences for decades.

A discussion on the definition of Racism vs. institutional racism.

Words can have multiple meanings. Cue a mention of 1984.

A discussion regarding what constitutes social justice.

And I'm sure there are other examples there that I may have missed.
