I deleted both of your comments, you and another user were engaging in a conversation that I felt was taking a non constructive turn. Others felt the same way, some of the comments were flagged as "rude/offensive". I'm not so sure why you think favouritism was at play here, I've also deleted a couple of comments by the other user. In fact the only reason I deleted your second comment was that it was obsolete, as it was replying to a no longer existing comment.
Comments on Stack Exchange sites are considered second class citizens. Think of them as ephemeral post it notes, their primary purpose is to ask clarifications and offer suggestions to improve a post; they can be removed at any time, especially if they become obsolete.
You can review our general comment guidelines in the "comment everywhere" privilege page, a page I now realize you probably didn't know existed, since you haven't reached the reputation threshold for the privilege. Apologies, if I had realized at the time that you were brand new to the network, I would have commented and explained the deletion of the comments.
