Dear Qwerty,
“The Gemara explicitly said that Nevuah ended during the 2nd Temple period and will not be restored until Moshiach comes.”
There is no such Gemara.
Where does that place you in your own belief system?
Why do you not answer questions directed to you?
Why does Chabad owe you any answers?
You clearly never made a good faith effort to try to understand them.
