I don't recall commenting on Rowling's literary abilities, but for the record: I think she's a competent, if somewhat clunky writer. I would never describe her as 'skilled', but that's just my opinion, and matters not a jot.
As to whether I want her jailed? No, I don't want her jailed, I'd much rather she and her bigotry just faded into obscurity. I don't think that her fame and/or wealth should put her above the law. By all means do all that is within your power to change the law if you think it's wrong, but while it remains the law, then it must be applied equally.
