<p>First of all, it is better to edit the answer (either to fix it or to make more obvious it is correct) than directly answering others' comments -- this way you have more space and flexibility.</p>

<p>Chat is in general a better place for discussions than comments -- system should have already suggested making a special room and inviting you and other participants of the comment exchange.</p>

<p>Finally, the fact that the post is downvoted does not mean at all that you should/must delete it -- this place is for sharing ideas and opinions about them, not to build a repository of bullet-proof statistical truth. Delete is reserved for a total junk or post <strong>you</strong> want to withdraw. </p>
