I dislike both answers, but for various reasons:
Tito Piezas III's answer
This answer is fine taken out of context. It's a perfectly good explanation that seems to answer the question, and it was recently accepted on Mathematics. My objection to it is that it is the exact same answer that he posted to the original question on Mathematics. I don't know the exact reasons that user 170039 cross-posted it here, but it seems to indicate that s/he wanted a different style of answers than the one(s) on Mathematics - including Tito's. In this case, Tito's answer is irrelevant - it's just re-posted information.
I took issue with this one for two reasons:
- It's a link-only answer. Nobody anywhere on Stack Exchange likes these. And the link was broken, to boot. I tried to find another to replace it, but that didn't pan out. So the information contained in it is inaccessible, which makes the idea of having users cite their sources pointless.
- It had a rant. Danu edited out a final bullet on it, but previously there was w third numbered section, ranting about how Indians are very forgiving towards the rest of the world. It (and possibly the other two points above it) is irrelevant.
In terms of voting - I upvoted Tito's before I realized his was a copy, and found myself locked in. After the edit, I tried to unupvote, then thought better of it and re-upvoted. I now cannot unupvote unless another edit is made. I did not vote on Advaitha's answer in part because I could not check the information, and was a little confused by the rant. It's up to everyone to make their own choices about voting, as it always is.
The thing I dislike about this whole scenario is that it was the result of what I'll call a "manual migration" - cross-posting from one site to another after the user decided it would fit better somewhere else. user 170039 could have asked the Mathematics mods to migrate it - after all, it's only two days old - and everything would be fine. But now we have a duplicate answer, a rant and a meta post about it all. This is not the optimal situation.
We technically can't close this question. It's not a duplicate of another answer on HSM, it's certainly on-topic, it's quite clear what the OP is asking, it's not too broad, and it's not opinion-based. We also can't reject a migration, because - as I said before - it's not a migration. In terms of resolving this, our best shot would be to get this question deleted from either Mathematics or HSM. The problem is, there's no rationale to do that on either site - it's fine on both! At the same time, though, the cross-posting is an issue.
My suggestion is that we let new answers come to the question here. We'll get some, I think. I don't think that we should keep Tito's answer, and I don't think Adhvaitha's should be kept here until the link is fixed. So I would delete both answers for now, and let the question evolve. They can be undeleted later, although Adhvaitha's is a better candidate for undeletion - Tito's is unnecessary.
I don't believe we have anyone yet who can vote to delete answers (and we probably won't have anyone for a while, reputation-wise), but pro-tem mods will be appointed in the near future, so they may be convinced to temporarily delete (and later undelete, possibly) the answers.
But for now, our hands are tied, unless we ask Tito and Adhvaitha to delete the answers.
Adhvaitha's answer (and some comments) were flagged for various reasons. I have deleted two comments that were flagged as offensive and considered deleting the answer, but I won't take further action until a consensus has been reached (which it may well have, being a consensus against my proposition). If the community wants to keep it how it is, I won't delete or otherwise modify the answer unless it is flagged again.
Two hours ago, the question was closed on Mathematics, so it appears our only choice is to keep the question.
