You don’t have to smack someone with a personal attack at the same time you enlighten them to unconsidered possibilities. Try leaving the attacks off and watch how things improve.
Sorry, but those who assume we must expect that any vehicle carrying a child is therefore innocent are idiots. Those who want to attack us are perfectly willing to blow up children in the process, their own if necessary.
To call those who refuse to recognize this possibility idiots is, I think, entirely reasonable.
