Liberal commenters are one thing, and without them this site would be boring.
The problem is twofold:
1. The leftist spammers who do nothing but repeatedly cut and paste garbage into every thread, making intelligent conversation/debate all but impossible.
2. The complete lack of moderation. Occasionally a comment or two that get out of control will suddenly disappear, but the spammers ARE NEVER IP BANNED.
For this reason we MUST have mods more like leftist sites(Huff & Puff) do, but not to that extreme. BOOT THE SERIAL SPAMMERS but let intelligent opposition voices remain.
