I have posted questions on Hinduism.SE.
Personally, I have a feeling that they are more open and flexible in accepting new questions, and the community is larger as a result.
On the other hand, Islam.SE seems to be extreme and rude. Any questions I am posting are being heavily down-voted and/or critisized.
The prime examples are the following questions:
Even the correct answers are being down-voted.
Why is there a difference?
You asked questions. You received criticism on your questions. This isn't "stubborn", or "extreme", or "rude", this is "the system working as intended".
Stack Exchange isn't a dumping ground for any old question; asking a good question — a useful question — is a skill that many questionaskers need to learn. Criticism and negative feedback are tools for this, but the onus is still on the questionasker to ask a good question, not on the community to hold their hand.
Just because one community has higher standards or lower tolerance than another doesn't make them stubborn, it just means that different people in different disciplines have different opinions on what constitutes "useful".
Now, to your questions in particular: Neither of the questions you linked show any research effort; on the face of it, it looks like you just read a thing and now you expect us to explain it to you because you were curious. This is just throwing all the effort onto the community to do all the work for you, and I'm not convinced they're particularly useful to anyone who is seriously studying the topic of Islam. I didn't downvote either of these questions, but I can easily see why people would.
Instead of blaming the community for your poor reception, why don't you try to put work into your own questions and maybe make them useful for anyone other than yourself? I would suggest exploring the site and paying attention to the questions that are well received, and taking your cues from that.
I apologize if you found my comment to be rude. It was on the first draft of your question where you wrote
"had it been Allah himself, he would not have said (so and so)"
Presenting an opinion as fact. My comment simply challenged this assumption. Criticism is meant to help you understand the flaw in your deduction and to improve the quality of questions on the site ... it should not be taken personally.
Please provide evidence of:
"Personally, I have a feeling that they are more open and flexible in accepting new questions".
Both of your question are "Why This/That". So you should be prepared for some heat/agression. Finding reason for why in Islam, usually leads to some agression.
For example a guy asked me "Why is usury haram in Islam?", one could comment "because Allah says it's Haram".
You may see comments like "do not question Allah decisions" or "Who are you to question Allah?". Which on the surface level may seem right as Allah does whatever He wills.
I encountered a similar comment on my first question as well but I think I encountered it.
I would not blame the entire community for some mean comments.
