The facts of the matter are as follows. Ayers served on a few committies with Obama. They have been described by Obama as being on friendly terms. Ayers was an early supporter of Obama's campaign. Ayers was formerly a member of the terrorist Weatherman group. So yes, he's friendly with a terrorist or former terrorist. It doesn't mean Obama himself is radical but Ayers is pretty radical. No one ever claimed they were best friends, however he is close enough to Ayers to be considered to be associated with him. The question you have to ask yourself, and the question every American needs to ask themself, is how closely associated to a terrorist/former terroris can a presidential candidate be before it is too close for your comfort. For me personally, his assocation to Ayers doesn't bother me nearly as much as his dealings with Rezko and his extremely close association with Rev. Wright. But it's not something I'm entirely comforted by either.
I realize you are looking for people to agree with you, but I thought I'd answer the question honestly anyways.
