The tech boss has attracted negative headlines after being asked a question about the company's rules around hate speech, which refers to any sort of verbal attack based on the grounds of race, religion, or another demographic.
Speaking in relation to the company's 2017 transparency report findings, one Reddit user asked the CEO: "I need clarification on something: Is obvious open racism, including slurs, against reddits rules or not? (sic)"
And Huffman replied to the question by saying: "It's not."
However, in a bid to diffuse any controversy, Huffman has since elaborated on his original point.
He said: "On Reddit, the way in which we think about speech is to separate behaviour from beliefs. This means on Reddit there will be people with beliefs different from your own, sometimes extremely so. When users actions conflict with our content policies, we take action.
"Our approach to governance is that communities can set appropriate standards around language for themselves. Many communities have rules around speech that are more restrictive than our own, and we fully support those rules."
By contrast, other popular online platforms like Facebook, Twitter, YouTube, and Instagram all have strict policies concerning hate speech that can lead to suspensions and bans.
