I want to have an adult conversation with you, but you always attack me.

I know every deleted comment can be retrieved. I have seen how-to's on how to do this.

I have 2 reasons for deleting some of my old (unwanted) comments:

(1) In an attempt to create a bigger and better echo-chamber, the brain-washed UFO/alien/ET believers often want to down-vote my comments, because the truth hurts them emotionally.

(2) I am not a Reddit super-user, and I find it difficult to find old valuable comments from my comment history. Therefore, it is in my interest to keep my comment history as small as possible, so that I can easily find some of my old comments that I may want to use again, because the same topics get posted time and time again.
