Eh. Most, though not all, of those were published in the 80s. And it's shitty, but it was a long time ago. I'm honestly much more disconcerted by RP's shifty treatment of them without adequately apologizing and taking responsibility for them.
People f'up sometimes. A lot, even. If I'm willing to give Jesse Jackson and Al Sharpton a break for Jew-bashing in the 80s and GWB a break for driving drunk and Romney a break for high school bullying, I can't see a reason not to give Ron Paul one too.
If, of course, he were willing to own up to making a mistake...
Yeah, except I don't give those people a break for such things. Anti-semitism is pretty crappy, no matter when it is; I know people who have been killed by drunk drivers; There are teenagers across the nation who kill themselves every year due to bullying. I don't see why I should give them a break at all for these things.
