The problem with this statement is that EVERYONE has their own perceptions. Telling people they need to "get past" something isn't usually too well received. In fact if we try to tell someone that they may just think we're an arrogant ass. In addition, if it does start to get popular there would be a lot of people and there would also likely be a lot of people that are not as reasonable as our community is now. Telling people to "get past" something likely would be ineffective and might actually make it worse. In addition, if there are posts out there talking about this there is no way to make sure new people have seen them. Even if they have, people have their own perceptions, and their own opinions so trying to push your perception and opinion as the correct one is not realistic. So what can we do?
I've said it would be nice if there was an introductory video people could watch when they create a new account that tells them some of our communal values such as "if you get flagged, don't let it bother you, etc." Try to introduce them to these concepts rather than just expecting everyone to "get past" something.
Well down-votes are a part of the internet. The only reason getting flagged is so poorly received here is because we have made a downvote into something which is like a negative badge a post has to wear. You are reading too much into the term "get past." What was intended there is that we have to as a community get back to the mindset that a downvote is a normal thing, because it is everywhere else on the internet, and if and when the community grows huge, people will use them as such.
This is called an Appeal to Tradition. It is a logical fallacy that doesn't prove anything. It is the fallacy that "because, a thing has been a certain way we should continue or it is true". In reality, they have not been "part of the internet" for that long. I remember a time not long ago when the up vote/down vote didn't exist. They are actually a fairly recent thing in terms of the internet.
In addition, they are really only a THING on certain sites like youtube, and reddit. In fact, I wonder which one of those was first. I suspect youtube.
My issue with "get past" is you like many people before you are assuming because you know a thing everyone else should know a thing. You are assuming because YOU can get past a thing that everyone else will be okay with getting past it. You are also assuming that because you use down votes so will the people that come here.
As far as down votes and the appeal to tradition. As far as I know no where else has it so the down vote impacts any monetary gains. This makes it a force multiplier.
I don't ASSUME people are going to be of a certain behavior, and certain perception on down votes. If this place takes off like we want it to we are going to have a lot of people. We have a pretty reasonable group of people now, and down votes are an issue. What happens when/if the masses come here. I am not anti-down vote for myself. I've only ever had the asshole bot down vote my stuff. I've seen how it has impacted other people though and it is likely an issue.
This is absolutely not true. It is in a few places on the internet.
EDIT: I am also not saying get rid of the down vote. I simply think we need to find a way to help new people GET whatever way we end up with, without ASSUMING they will get it. That assumption is already proving to often be false with some of the existing people that come here, and even some that are here for awhile.
EDIT 2: Out of curiosity I did a quick google search. Not comprehensive, but it did remind me of a few other sites that have the up vote/down vote. It is not EVERYWHERE on the internet by a long shot. It is mostly youtube, and reddit. It is spreading to other places. Imgur is another place that has it. I didn't check Pinterest, but possibly it has it as well.
I know facebook doesn't have it now. I can't remember if they once did, as I stopped using facebook long ago.
