Lemmy is a fine place for it, saying it’s a hive mind may have some truth, but it’s also a copout. Just back up controversial opinions with some sources.
You said you read things that “got you to this point.” What was it you read? I’d be interested in reading it.
By comparing people to these slurs, you enforce societal norms that indicate that the said group has less value in society.
Since humans are social creatures by nature, you are essentially dehumanizing an entire class/group of people because you can’t come up with something more clever to say.
To err is human, we all make mistakes, intelligence/sight/etc. has nothing to do with it.
