I heard the full 14 min speech. There were far more people supportive of him (ones who applauded when Vivek asked them to applaud) than the few loud Nick Fuentes’ d~k sucking incels.
Overall it was a pretty good speech but the clips making the rounds on X are the edited versions showing the booing and Vivek walking off stage. Vivek wasn’t “booed off the stage”. He finished his speech, shorter than usual, and then walked away.
