If other evidence comes up of this news reporter faking stories, then I'll agree this is not trustworthy. If any report comes up that Bush said atheists can be good citizens, then I'll agree this is not trustworthy.
Instead, we have an official response that Bush will have "due regard for the legal rights of atheists". I'm sure Bush also had 'due regard for the legal rights of convicted felons' (single quotes to indicate paraphrase). I'm underwhelmed.
Anyone who thinks it was in any way politically risky to slander atheists in 1987 has forgotten how the country felt about atheists back then.
