Hate speech is a priori not very reasonable so getting rid of it is not a matter a censorship but of getting rid of what stand in the way of thoughtful discussions.

Also I don't think "in my house" metaphor has had much success. Which seems fair : Hacker News is not PG's house, although it is his baby, he handed moderation power over to the users, the algorithm and the moderators. Which is why we like it and trust it and use it. You can't just compare anything to one on one relationships, it does not work like that.
