The problem there is the claim they're ideologically opposed to any walk outs. If that were really true then they would even platform extremists claiming for instance that everyone non-white should be classed as sub-human and not be protected by law. If someone objects to a walk out in that case there would be no question that they were grossly negligent at best.

So then assuming there is some level of competence the next question is why has the line been drawn here? Why platform people trying to strip rights from this specific marginalised group? The only reason would be that you to some degree sympathise with the hate and believe there is value in discussing whether this group deserves rights.

Neither case paints them in a good light. Unless you're on the side trying to strip people's rights, of course.
