No you are not, you might be deluded into rationalizing this but your purpose is not to help others, I suggest you take a moment to really look at your motivations, ask yourself first "why do his post irritate me" then "is it worth my time and energy to be irritated". Follow with "why do I feel the need to address this publicly and repeatedly" then "how do I feel after posting my response (does it work ? Make you feel better? Is the gain worth the cost of time and energy?) Finish with "what could my secondary gain be?" You receive a lot of negative attention! Does that excite you or make you feel better about yourself? I promise if you give this a little time and effort you will discover why you really do this and may find that it's not worthwhile , then again you may find it is! Just don't lie to yourself or others about your purpose- just looking out for you.
