See just under your comment, you have the ability to delete. you can also do it by clicking the name up in the right corner and then find the comment and delete.

but you could also learn not to talk that way about a "sensitive subject" as you put it. as sensitive as it is in your words, you're treading on it like a moron. and what is up with your name.
don't worry your here, but if you are here to speak crap then get a more suiting name. see if /u/ImMadAtYou420s is available
