For example, if I talk about “magic”, most of you will tell me I’m wrong without even asking me what I mean. You might even insult me.
How common is this? How much of this conversation is actual communication vs just a string of triggering phrases that we react to?
How much of Lemmy is people just barking at their own echo?

You didn’t want to engage unless it was with people who agreed with you. You also wanted to filter the conversation to only people who believed in magic. When I, who met all three criteria for your post but who has moved past magicope replied with a very standard materialist position, you replied with a pithy comment like this post and dipped out firing a “I GUESS YOU DONT WANT TO DISCUSS” over your shoulder as you left. Grow up.
