My post was not intended to be inflammatory. The majority of people asking the type of questions you have been posting are usually working on some sort of project (whether for a speculative zoo or building a real life zoo) rather than just asking for curiosity's sake. As you've asked multiple questions along a similar line, I was curious whether you were seeking information for something versus sating curiosity.
Bear in mind this is a discussion forum, not Reddit or somewhere else that you post a question and get answers handed to you from random people. Here many of the same people are seeing and answering the various questions, and so there's more opportunity for curiosity to arise. Making a number of similar-themed threads seems to have a lot of people wondering why these specific questions.
If us asking "why these questions" out of curiosity is enough to make you feel 'attacked', consider that many in this community will ask for sources, additional information, or other resources depending on the situation. If it's just curiosity that's fine, but why was there a need to be so defensive? I was not intending to be inflammatory, I was curious as your questions are in a similar vein to those working on projects. It's not unreasonable for someone to ask "why these questions" on a discussion forum. It's often to get a better understanding of the situation we're answering to.
