The person you’re responding to said “designed to promote hate speech”. Your examples don’t sound like that.
A forum dedicated to the principal and culture of free speech is designed to promote hate speech?
Btw, a forum dedicated to the principle and culture of free speech would absolutely (by definition) be promoting/hosting hate speech.
What is your personal understanding of the term?
The alternative is to accept that moderation is NECESSARY for online communities (or else spam and hate speech will take up a huge part of the content and suddenly you'll realize you're essentially promoting this content afterall) and moderation will always look like the opposite of "free speech".
