Well, I may have used that word mistakenly. I meant "source of the problem". If that's an insult, then there are no other in my comments, I do actively refrain from insulting both online and in person. As for criticism, yes, my comment is a criticism, and tries to be a constructive one. I spot the problem, I suggest a solution, I may well be mistaken, but there are no insults. And I comment on the situation, not ad hominem.
