While I agree with the sentiment that thinking of somebody like McVeigh as an absolute hero, I don't think the reason for that should be hinging on the fact that children died in the attack. It's a bomb. It's about as non-discriminatory as weapons go.
Assume no children died, would that somehow qualify him as being a hero after all?
What about teenager Cartney McRaven, age 19?
What about Kathy Cregan, Rheta Long, Laura Garrison, LutherTreanor, Olen Bloomer, Calvin Battle, Norma Johnson, Donald Burns Sr., Donald Fritzler, Eula Mitchell, Anna Hurlburt, John Vaness III, and Charles Hurlburt - who were all probably looking forward to their retirement or were otherwise just at the wrong place at the wrong time?
What about the 135 other people who don't fit the criteria of child, teen or 60+?
Timothy McVeigh was a murderer, period. Read that, and tell me again about his heroism.
While we're at it - let's not start thinking of weev as a hero either. His mentioning of McVeigh could just as well be part of his usual trolling, which borders on the distasteful at best.
