Crowder was harangued by Maza for years, Crowder responding by doing a mocking impression of the self-referential non sequiturs that Maza would proclaim amidst his criticisms seems like fair game and not homophobic.
I don't see how it is any worse than when Crowder mocks Trump's braggadocios by imitating his common catchphrases. Such material is low comedy, for sure, but not cancel-worthy.
