I am civil to those who are civil to me. Making unsubstantiated allegations of disruptive/bad faith editing is not civil; I don't do it to others and others should not do it to me. And if I respond with sarcasm that's the least of what they should reasonably expect for such antagonistic behaviour. And that move was a mistake, it was not vandalism, as you are aware''', but don't let that stop you making more unsubstantiated bad faith allegations.
