Posting it as such would have allowed @ClarkLyons to change the question to what was or should have been meant, whereas the etiquette has it that changing a question in a way that invalidates answers should not be done. | |

However, it is absurd to claim that it is not actually an answer to the question (as appearing in the title or in the body text: "Is it always the case that there are more conjugacy classes in the kernel of $\phi$ than conjugacy classes not in the kernel of $\phi$?"). | |
