Let's cut to the quick: So-called "religious arguments" are never between Hindus and Pagans, nor Buddhists and atheists. It is always Christianity, the intellectual caliber of the anti-Christian normally involving little more than "I hate your sky god." And, that's sufficient to get a thread closed.
Marxists attack Christianity relentlessly. They do not attack Buddhism relentlessly. The attack on Christianity is among the primary efforts in every Marxist agenda.
Without Christianity there is no traditional Western culture. No credible historian argues otherwise. Arnold Toynbee once wrote that "Western civilization is inseparable from Christian civilization."
The Daily Stormer (DS) rule should be 'no preaching.' Yet, I can think of only one participant who does so. Inter-denominational vitriol should also be prohibited.
"Religious flame wars" should be interrupted by forum moderators. That's what moderators are for.
Although I think "religious flame wars" a misnomer. It implies there is something of substance committed from both sides.
If DS site management advocates other than a Christian perspective, it advocates other than traditional Western culture. If site management disallows the Christian perspective in discourse, under the umbrella of prohibiting religious discussion, it is pandering to those who - aware or not - would have other than a traditional Western culture.
Lastly, it has been my experience that most discussions termed religious by DS normally resolve themselves.
