<human>: Sometimes people are dickheads, and its okay to downvote those people, and sometimes people are smug assholes and are wrong, so I suppose its okay to downvote those people too, but it really drives me up the wall when there's a comment where clearly the person missed the joke or was wrong but just trying to be helpful and they have like -20 points for it, *and yet no one has explained why they're wrong*.

I saw a thread the other day about how a hotel got rid of their 420 room number (because presumably people would go in there and smoke pot), and in the comments there was a comment saying something about how 4 and 20 are bad luck in some other culture (I don't remember the exact comment), and he made a comparison to buildings not having a 13th floor and that that was probably why the hotel changed the number. Clearly he didn't know 420 was slang for weed. His comment wasn't smug or condescending, he believed he was just trying to shed some light on the odd situation. Dude had -30 points for that comment. *And no one had even tried to explained it to him*.

I feel like Reddit craves this ability to shoot people down to stroke their own egos, "HA! This guy's so stupid! Even I knew that! DOWNVOTED!". It's not about the karma, it's just about the sentiment. If you were at an art museum with some friends and your friend said something about Van Gogh living in the 1700s, you'd probably say something like, "Actually bro, I think he lived in the late 1800s". You wouldn't all laugh and him and call him an idiot.

<bot>: It all just irks me sometimes. Is it really too much to ask that we all just be nice to each other?
