"READ MY DNI" no. use your block button like an adult. i'm not scrolling through the many-paragraphs-long pinned posts of every blog i reblog something from. if you insist certain types of people aren't welcome in the notes of your posts then it's your responsibility to curate that. or choose a closed social media platform like facebook or instagram. or go and live in a barn away from humanity if you really don't like sharing the world with people who are different from you
I think that DNIs are a really clear example of the backwards understanding of boundaries that a lot of people have. Some people think it works like:
"My boundary is that YOU can't do this thing I don't like"
When really it's more like:
"My boundary is that if you do this thing that I've told you I don't like then I will remove myself from the situation"
The former does not work. The latter is more effective, it takes responsibility for yourself, and also it puts the power over your wellbeing into your hands and not in the hands of strangers who may or may not be malicious.
