How do we deal with this behavior, and what is the term for it?
[POSTSCRIPT: this post is not about any one individual question, or answer, or comment, or downvote, all of which are irrelevant, as am I and any average individual SO user. It's about the widely-repeated pattern of behavior I see every day when I look at SO; specifically can it be changed, or if you think it can't be changed, how much it degrades the quality of posts on SO. This MSO post currently has +15/-24 votes, so quite a few people out there agree with me. Feel free to disagree, just stay civil; disparaging comments and flames will be flagged as such.]
It all starts with this question
I post a valid answer which is arguably better than the third answer for the reasons I state (for what it's worth, I independently found
random.choice() in the doc before it was posted).
Then one of the other answerers picks a bogus argument with me claiming "using objects is not OO", which is not a relevant criticism, and frankly as obnoxious as it is condescending. I object, then mysteriously my answer gets downvoted within at most 15 min later. Not wanting to get into downvoting wars.
(My query about why the user thought they should use
random.seed() stays unasked; I prefer not to rush out an answer to 'Give me teh codez now' questions until the asker clarifies what they actually want. Sure if I had simply rushed out an answer and hoped it approximated what they wanted, I would tactically maximize my chances of getting the thumbs-up, without clarifying their thinking, and clogging up SO. But back to the answerer.)
As to the other answerer's behavior, this sort of hit-and-run nonsense degrades SO, how do we deal with it? Why should I spend my time addressing the OP's question if my only reward is this? If anyone wants to back up the claim that my code 'uses objects but is not OO' (or that OO is undesirable on this task), I'm still waiting for it. I guess we could develop a blacklist of users who react like this. It's simply destructive behavior. I mean sure I could flag the comment, but then it goes away, and all that's left is a downvote.
