Why do you think being frustrated because of a perceived injustice by "harrassers " , gives people the right to act out on their frustrations in immature and hostile ways?
If rules are not enforced on the initial abuser, the victim ends up with no outlets to feel safe other than complete retreat or retaliation.
If the reason for the lack of enforcement is lack of communication and pressure on mods to act on said communication, the President is in fact a very good role to both gain the trust of users to turn to and to push mods to act knowing that if they fail to act, then the victim who retaliates won't go down without the President ensuring that the negligence of the mods is sufficiently held to judgement by the userbase as the President is supposed to not allow such things to be swept under the rug, contrary to your belief.
Why do you think those people deserve any special defense, once they begin lashing out?
I intend to defend absolutely everyone, from the harshest to the tamest so long as they understand that it is also their duty, now that they know they're protected, to be kind and protective to their fellow user. The entire environment will shift, it just takes the right kind of pressure.
