Yes, if if you don't take writing seriously. And no if you are interested in writing, you should not leave hubpages. What you should have done is to sit down again and rewrite your hub again to make it worthy of being published at hubpages. Hubpages are strict on what we post here. We are supposed to produce high quality articles and no duplicate material.
So, sit down and rewrite your article or shelve it for the time being and write an entirely new article. Make sure you have read the guidelines on how to come up with a winning article from the Hubpages Learning Center.
Remember, even if you decide to leave hubpages, the only place perhaps you can publish substandard work is in your personal blog.
Don't give up.
