DaMoshe: that was a really cheap shot. Chasidish Rebbes are very makpid on Zman Krias shma and demand their followers to do likewise. Ask any Chasidish bochur what’s stressed before bein hazmanim.
If you would have mentioned davening shacharis late or mincha after Shkia, maybe you would have come across as sincere. The reason some very great Rebbes used to daven shacharis late is because they didn’t feel spiritually ready and had many hachnosos before facing Hashem in prayer. It was never a blank check for the klal.
Just to clarify, shma can be said privately at first to make the zman. Not ideal, but not changing halacha.
