No, not at all.
Timothy Mcveigh was an act of domestic terrorism.
Sandy Hook elementary was not. That doesn't mean that it wasn't an unspeakable tragedy.
My point wasn't that it couldn't be someone of any denomination, creed or color, it was that recent terrorism or terrorist threats have been mostly been led by Islamic extremists and to simply throw out the notion that it couldn't be them - is silly.
If the Time Square bombings actually took place, this would be an entirely different conversation, but since 9/11 is for some a distant memory of the past, this sentiment is being poo pooed.
Their threat is still present and to think that what we experienced 10 years ago was the last of it, is foolish.
