Absolutely, everyone should have the right to talk about any topic.
I think the problem happens when famous people come out about topics for which actual professionals have deepened opinions on the matter, so the problem is that a famous person leverages their fame to push their opinion and that is where it's lousy.
It would be much better to hear someone who is famous for their life's work on gender identity than to hear the writer of a children's fiction novel. Her opinion is probably just as good as ours.
Well I'm very much against giving attention to celebrities opinion in any topic. They are famous for role playing or stuff like that not in politics, economical, etc.
