I downvoted your answer to What's a concise "I'm not dangerous" phrase for a business card?. I was put off by the combination of 2 things: the sarcastic tone at the beginning, and what I felt was poor general advice for the rest of it. Either element alone normally doesn't get a downvote from me. We have plenty of answers with a sarcastic or snarky quip, but those are usually followed up with a more light-hearted, or knowing/winking "I'm being rough, but let me clarify..." type of full explanation. And there are a lot of answers that I disagree with the advice given, but not enough to downvote (it's more of a "meh" response from me).
So to me, your answer came across as slightly dismissively sarcastic, with advice that I feel doesn't help the photography community as a whole, or photographers individually. Combined, those factors almost met my downvote threshold. I "rounded up" to the threshold because I wanted to discourage that answer and that type of answer.
On the subject of the questions you've asked, I didn't downvote any of them. Personally, I think they are interesting conversations or debates. But they are particularly poor questions for the Stack Exchange Q&A format, so I voted to close them. They are fine forum discussions, but Stack Exchange is not a discussion forum.
From this site's help center, What types of questions should I avoid asking?:
You should only ask practical, answerable questions based on actual problems that you face. Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page.
If your motivation for asking the question is “I would like to participate in a discussion about ______”, then you should not be asking here. However, if your motivation is “I would like others to explain ______ to me”, then you are probably OK. (Discussions are of course welcome in our real time web chat.)
To prevent your question from being flagged and possibly removed, avoid asking subjective questions where …
- every answer is equally valid: “What’s your favorite ______?”
- your answer is provided along with the question, and you expect more answers: “I use ______ for ______, what do you use?”
- there is no actual problem to be solved: “I’m curious if other people feel like I do.”
- your question is just a rant in disguise: “______ sucks, am I right?”
The questions you've asked fall into these categories, in my opinion.
Like I said, in a different context (meaning forum, not a Q&A site), I like your questions and the discussions they would probably generate. It's clear you have a lot of experience, and I think you probably have some great answers in you just itching to come out. I hope you stick around — I'm looking forward to seeing them.
