You can point out to others when you are attacked inappropriately by thanking your attacker for their ad hominem attack on your intelligence, integrity, or whatever it is they are attacking. You can show that you have recognized their ineptness at making honest arguments and have resorted to name calling as a way of admitting they are not able to logically state their position with factual and informative posts. Don't make the same mistake yourself by remembering your an adult speaking to a child who knows nothing about common courtesy or decency. Do not let them make you respond in kind. You have all day or even all week to respond. What they have said was in haste and people see this.
