Voice impressionists or those that try to be ones, such as Mario Rosenstock, Oliver Callan, Doireann Garrihy have made careers out of doing voice impressions.
These are essentially efforts to mock someones accent, voice and speech.
Take for example mimicing Bertie Aherns speech. Bertie has a stammer which is cruel to mock someone for a speech impediment. Michael Flatley has an Irish/American accent mix which is mocked. Joan Burtons high pitched voice was routinely mocked for years. Joe Duffys strong Dublin accent is routinely mocked. Jose Mourinho speaks great english yet is mocked routinely by impressionists by pronouncing nothing as nussing.
I'm not saying I support them being cancelled but you'd think it's inevitable.
Similarly, I'm surprised the Little Britain guys David Walliams and Matt Lucas haven't been cancelled. They created transphobic, homophobic, fatphobic, xenophobic yet they've not been targeted by the usual crowd and still have careers.
