I agree with what Rodrigo says: you don't have to include a paper which you do not like in your CV.

In general, people are usually evaluated by their best papers not by the worst.

From my own experience, I can conclude that my own opinion about my papers does not always coincide with the public opinion. There were several papers I hesitated to publish, but they are more appreciated than some papers I am proud with.

There were also results I did not publish, considering them too light-weight, and later had regrets.

And finally "toxic subject" is on my opinion a nonsense.
