Social media is like anything on earth, i. e., estimated thoughts with the content of the ego wrong mind. Online attacks locally for a Course in Miracles (ACIM) are via the many comments, quotes and other lists whereby we respond to our model which then becomes the approval for our response (T-12. I. 1) or our reason for posting, etc. All students have a basic confusion between form and content as well as what it means to join so let's not sugar coat it: Social media is forms (projected content of the ego wrong mind) from joining with the wrong mind. Therefore, from the outset it is a series of attacks until we eliminate and start identifying (joining) with the right mind.
Even in the Course, we all sit around online with some sort of a digital device mindlessly doing our ego thing. Okay, some might be standing Curso de Milagros, leaning or lounging:
Sitting around and talking about the Course is different thing as doing the hard work of studying the written text and putting the principles into practice to find out what the Course means (Kenneth Wapnick, Rules for Decision).
In the same Rules, Wapnick also says, "What provides the ego its power is your having joined with it, your identification with it. inch Forms are estimated as a defense contrary to the opposite and are only with the ego wrong mind and thus they don't matter.
Since social media is all about forms which are fragmented projections of the ego, we are then perceiving the Sonship as fragmented which are the error real. Specialness is valued as an idol placed before the Love of God and those perceived differences take care of the splitting up in the mind. Absolutely any fragmented feature we judge in another online (or anywhere) must be welcomed in all of the Sonship since we're really One in reality. That is why attack isn't under the radar and must be relinquished (T-7. VI. 1).
Under the radar means, "Individually separate and distinct. inch All attack in a form is the same and is meant to partition the entirety of the Sonship because it attacks (fragments) the Sonship via differences instead of sameness. Hence, we can see why Wapnick would say that it is silly to use the Course as a weapon when it's clearly an application located in unity.
