Think about it: you try reasoning with them, then get tired and block their noise from your feed, but all that does is reduces the presence of the ‘readonable minority’, allowing them to spew their rethoric to a more receptive audience. Socmed sucks.
Blocking on Lemmy doesn’t prevent them from seeing your “reasonable” takes. It just hides that user’s messages from you. They wont even know you have blocked them.
