sure, some authors do use that term in the same way you used it.
http://preservingwesternciv.com/purpose.htmlStatement of Purpose:
We believe that America’s Judeo-Christian heritage and European identity must be defended. Today, our glorious Western civilization is under assault from many directions. Three such threats will be discussed at this conference. First, the massive influx to the United States and Europe of Third-World immigrants who do not share our fundamental political and cultural values. Second, the threat from Islam, a militant ideology that is hostile to our society and, in principle, committed to destroying it. Third, because of the persistent disappointing performance of blacks (which many whites mistakenly blame on themselves)
many whites have guilt feelings that undermine Western morale and deter us from dealing sensibly with the other threats.
