I thought it was OK. They had on Kate Shanahan, journalism prof from DIT, who discussed why it's such a heated issue and editorial decisions when making a show like Prime Time; Ellen Murray from TENI, who gave the line you would expect (pro-affirmation, critics don't know what they're talking about) plus Stella O'Malley and her own personal story of wanting to be a boy when she was a child. All quite calm and reasonable to my mind.
I see there's a demo going on outside the RTE studios:

Interestingly, few if any of the protesters appear to be obviously trans. Obligatory woke beardy blokes and a bluehair are in attendance, of course.
