It'd be a shame to have a president who condones torture. I mean - another one.
Seriously, though, it's hard to take this kind of criticism seriously from someone who has cited davidduke.com (or maybe it's .org, who cares?) as a source.
That is - coming from MaGZ, this can't really be interpreted as "She shouldn't be allowed to be president because she supported a domestic terrorist organization," but rather "She shouldn't be allowed to be president because she supported the wrong domestic terrorist organization."
Personally, I'm not a fan of violence, and therefore, not of the Black Panthers. (Also not a fan of Clinton - a separate issue.) However, the Panthers are almost infinitely better than the KKK, and considering also the level of Clinton's support (according to the Snopes article, I mean - newsmax and freerepublic are not reliable sources), along with the fact that she didn't appear to do anything illegal at all, even accepting the worst interpretation - no, she obviously shouldn't be disqualified from the presidency for this non-issue.
