The title was incomplete and thus misleading, the body didn't show any research effort, and the question was a bit disconnected: the downvote and the "unclear" vote were warranted.
You tried to salvage the question by completely rewriting the post, which is great, assuming you really understood the question (remember not to change the intent of OP's post while editing it, however wrong/misleading the post is).
But it's never someone else's job to do the need to fix OP's post (users are encouraged, but they are not obligatory).
So, answering your points:
- Which is more †welcoming, my action or the other user's?
- Is the other user's choice of the silent, anonymous double-whammy, without any comment to the OP indicating the reasons or how to help more than just unwelcoming? Could that perhaps actually be discouraging to non-native English language users?
- Your action seems more welcoming, but that doesn't mean the other user is unwelcoming.
- Downvoting and close-voting are for curation purpose and they are not personal. While it might be best if anyone should provide constructive comments, it's never mandatory (otherwise SE has enforced it since the beginning). Non-native English speakers (like me) are already in disadvantage because SE is an international site that enforces English as the main language, but that isn't really related to this case.
