What do people think of Stefanos Kasselakis?

I went to Athens last year and planning a trip to see Philip of Macedon's/ Alexander the Great's palace in Macedonia this year. I'm gay so naturally been Googling Greece and being gay/ gay bars in general 😅 And I discovered Stefanos Kasselakis. He seems like quite a character. And being an openly gay leader of a major political party in Greece seems like quite a statement in itself. Could he become the prime minister?
