Hell, GUEST, I don't even know who "they" is!! But I do know what Aesop, the Greek fabulist, said about those who snipe from the safety of an unreachable location.The Kid and the Wolf
A Kid standing on the roof of a house, out of harm's way, saw a Wolf passing by and immediately began to taunt and revile him. The Wolf, looking up, said, "Sirrah! I hear thee: yet it is not thou who mockest me, but the roof on which thou art standing."
Time and place often give the advantage to the weak over the strong.
