I copy word-for-word from Lubavitcher site Crown Heights Info here (who else but antinomian Lubavitch would still be proud of this today?!).
“Cancelling Tishah B’Av” by Rabbi Sholom DovBer Avtzon
The custom used it be that whenever there was a celebration such as a bris or wedding, a friend or relative would honor the guests with a drink of beer or a similar beverage. There was once a bris on Erev Tishah B’Av, and no one brought any beer. This was as a precaution so the participants would not become intoxicated and be unable to daven Maariv and say Eichah and Kinos properly that night.
The Zeide, who was also at the bris, asked loudly, “Who is honoring the participants with beer?” Understanding that the Zeide desired that nonetheless beer should be served, one individual announced, “I will distribute beer.” He went home and brought a large quantity of beer, giving each participant a full cup.
Seeing that everything that individual had brought was finished, the Zeide asked once again, “Who will honor us with beer?” Once again someone replied that he would do so, and he gave everyone another full cup. This repeated itself numerous times, and the people drank much more than they were accustomed to.
When night fell and it was time to daven Maariv, there was no minyan to be found. The gabbai went from house to house, hoping to bring some people to help complete the minyan. But in every house he entered the male adults were so intoxicated that they didn’t hear his request.
The Zeide walked around the shul snapping his fingers and exclaimed, “Master of the universe! I interfered with you. I am telling You that to be able to help a Jew forget his troubles and sorrow even for a short while is more precious to me than Your Kinos and the entire Tishah B’Av!”

Who knows if the story is even true, but have they no shame to repeat such gidduf garbage aloud about someone they respect?!
That’s “Chassidus” in a nutshell for you!
