Sorry, not a native English speaker.
Is there some kind of scale of Birtherism or Trutherism or anything - or is it just all or none?
Most people can safely say that a remote controlled holographic image did not fly into the towers - but are we allowed to wonder about events at all?
Same with Birthers - some are off the deep end - others have questions that seem reasonable.
I think that a lot of people have questions or opinions about subjects - that they sometimes supress so as not to be labeled a whacko by someone else.
I think the people who speak out about their questions are kinda brave actually. They may be misguided or wrong - but I think it’s better to speak your thoughts rather than betray them.
