I took great pains to avoid the majority of the media interpretations of this past campaign cycle. I didn't start researching candidates until October, and then I mostly relied on BBC. I have some degree of confidence in their impartiality and lack of partisanship. There's a lot of crap I didn't hear about until after the fact, and a lot that I'm sure I still haven't heard about.
ETA: The "star of david" thing seems like reaching to me. 6-pointed stars get used a lot to make fancy text boxes, they're a canned shape in any word product. 4, 5, 6, 7, 8, 10, 12, 16, 24, and 32 point stars are all standard. I don't think that the inclusion of a canned standard shape is necessarily anti-semitic. If it is, I'm screwed, since I've been using them to call out important info in powerpoints for years now. Given that they quickly replaced it with a circle, I'm inclined to say that it was not intended to be anti-semitic, and that they showed some degree of sensitivity to that interpretation by moving to replace it.
