If you confidently say something out loud enough times it starts becoming pretty embarrassing to backtrack on it. If they can’t even come up with a justification that’s convincing in their inner monologue, they’ll have to either backtrack on being pro-Trump or being anti-pedophilia. This might sound absurdly optimistic, but I actually think most magas would have an easier time revoking support for Trump than saying they don’t care about pedophilia.
