What would you react like if your partner supports beating children ?

So , let's say you are dating someone and they happen to support schooling children the old way , I mean to say , hit them and scold them like the previous generations did because they believe that is what has brought the best out of this generation .I personally prefer communicating and grounding children over old school methods as it'll give them a sense of safety instead of fear of parents . How would you react to this opinion ?
