Curious that he mentions the "widows and the orphans" (a refreshing Biblical reference). In that context, does he think "this strain(!) of libertarianism" is "dangerous" because he feels that the aforementioned would be left to fend for themselves, without any [government] assistance, as if that it the ONLY assistance (never mind about how effective such assistance is)?
To be frank, I do know that it is my Christian duty to aid the widows and orphans, and am not opposed to the idea using my taxes for that purpose. The funny thing, though, is that instead of doing the work of Christ, our taxes usually go to filling the pockets of Judas!
