She was real, she is dead, her family is in mourning.
No, because I do not need to see a wingnut video where someone claims Sandy Hook was a hoax. If it was, the amount of people who would have to be in on it would be absolutely staggering - numbering in the hundreds, if not thousands.
Someone posted crap about that same video here (before the thread got zotted) the other day & it did not take long for those who watched even just a little of it to point out the factual flaws & leaps of "logic".
Tell me, is it your contention people did not die that day in Sandy Hook? Or are you the subset of wingnuttery that knows people died but believes it was part of some grand scheme orchestrated by students, families, school administrators, townspeople, police, the coroner & city officials, and Obama?
