I’ve received way more bitter and raged out responses here than I’ve ever received on Reddit for very lukewarm vanilla takes. I’m not saying Lemmy is full of extremists but there is a user base here that is all or nothing. My guess is it’s age related though.

The version of someone you invite in the door determines the initial trajectory of how that person will act in the community. You can invite in the leading edge of someone’s developing kindness or invite in the ossifying mass of their nature that is threatening to turn hateful and uncaring. No one instance of invitation to a new person (however that may happen, formally or informally) pushes the needle far either way within any one particular person (though sometimes it can radically do so) but the overall integrated effect is a moderate shift of the an entire community towards the better or worse version of the community members. When this effect is used for good people often describe the resulting community space as a community that accepts them for who they are or more succintly is a genuinely safe space.

Of course, every interaction is in an invitation in some small way, it doesn’t just happen once.
