“I did not daven in my small CT town Chabad but they had the banners and picture in the lobby, not shul”
You’re saying a small-town kiruv Chabad had yechi banners in the lobby?
“why is it that in almost every single picture of rabbi shneerson that shows him wearing tfillin do the tfillin shel rosh droop well below his hair line and on to his forehead?”
Interesting observation; I had to look up pictures to confirm that it’s true. In any case, if I saw a random nobody at shachris with his tefillin like this, I would just assume he initially put them on correctly, but they drooped. All the more so, I would make this assumption for a major rabbi. It’s almost harder NOT to be dan l’chaf zchus in this situation since the most likely scenario is just that tefillin move around and come out of place every now and then.
It might happen more often for those that use jumbo-tefillin like Chabad. See pictures of Dayan Yechezkel Roth, a very respected non-Chabad posek who also wore jumbo tefillin, and you’ll see that they also drooped, almost to his eyebrows. In pictures of HaRav Kanievsky, the tefillin shel rosh are also almost always positioned like the Lubavitcher Rebbe’s. HaRav Elyashiv, same thing in some pictures. Maybe your question should be why we’re all so finicky about it when clearly most gedolim are/were not.
My point is, find a better thing to pick on them for. Something that clearly happens to the best of yiddin routinely is not a Chabad-issue.
“Here is my question for you, is Elvis still alive?”
Actual question for you, and I’m genuinely curious: if you met an Elvis fan that believed he was still alive (as many actually did), would that person be a koifer or eved avodah zarah? I’m of the novel opinion that the Chabad “still-alive-niks” are less of a problem with the Torah than the “techias-hameisim-niks.” Most people seem to hold the opposite, and I don’t understand why.
