As I pointed in comments, your answer is purely political and doesn't address the question. Read the question again:

Political and scientific Q/A is off-topic here. See the FAQ. So, your answer is deleted for being off-opic and not answering the question.
It was not deleted (by moderator) as rude/offensive but was flagged (by user) as rude/offensive and that's why it was showing like "marked as rude/offensive" status-bydesign.
To correct it, the rude/offensive falg is cleared from your answer and now you may check no such rude mark should be showing.
