Let's ignore any definitions of "strong language" for now, such as scolding, but I'll repost the comment here for permanence:
Please notice that this site has the policy that questions should show some own efforts. Therefore, please do not encourage users who did not show these efforts by answering them (until they did).
I can see that downvotes are a sort of punishment, if you were to take voting personally (which you shouldn't), but you are correct to point out that they are part of a trend that I will try to explain.
We've had varying levels of turmoil over the past few years regarding "homework" questions, which is referring primarily to copying and pasting the homework/exam/etc. question verbatim into the Chem.SE question box (or taking a screenshot that may or may not be rotated properly...) and expecting an answer. These questions are almost always a bad fit for our site, because answers generally don't provide useful knowledge for anyone other than the asker, so they shouldn't belong in a collective database. We could debate about the definition of "storing all the knowledge of chemistry", but this would lead to the proliferation of many nearly identical questions that don't add much once you have more than a few.
The problem is that we have many, and the way we "get rid" of them usually is to close them, usually via the homework reason:
Homework questions must demonstrate some effort to understand the underlying concepts. For help asking a good homework question, see: How do I ask homework questions on Chemistry Stack Exchange?
However, these questions can still stick around, depending on how many votes they have, if there are answers, and so on. Enter the Roomba, which is active on all Stack Exchange sites. One way to trigger the automatic Roomba deletion of a question (rather than having a moderator do it) is to downvote it and any answers it has. In this particular case, one of the answers is simply incorrect, and is being downvoted for that reason. Historically, we don't like answering these kinds of questions, though official verbiage about this is no longer present. The other answer is a casualty of the opinion that this question should be deleted, so it must be downvoted in order to activate the Roomba.
Whether or not you agree with this, the second answer being downvoted is most likely collateral damage. This behavior is becoming increasingly common.
