To be clear, the questions were on various answers to this question.
I declined the flags because it was an inappropriate use of the flags.
Answers can not be "bad subjective" - that criteria only applies to questions. The definition of a low quality answer is something that doesn't provide a reason or explanation, only consists of a link, it's commenting on the question or another answer, and so on. The flagged answers were well written and explained themselves, and I disagreed that they didn't answer the question - they did provide real world examples of the use of dynamic typing.
The only other reason to delete an answer is if it's abusive in some way, such as advertising with no disclosure, unrelated spamming, or is offensive or abusive toward members of the community.
In this case, the problem was not the answers, but the question. The question received 5 close votes for not constructive. It also received a large number of answers, which is something that could indicate a non-constructive question or a question that is too broad, since it could indicate that there's no right answer if people aren't norming on a few best ideas for the condition.
