I think everybody should just move on. The topic in question is a controversial one, about porn, and you can understand why a post may be deleted in terms of the website/Google/etc. If your post was deleted, I doubt it was because someone had a vendetta against you or wanted to silence your opinion, it was probably because you brought up a taboo topic or questionable content that is perhaps not appropriate (and no fault of your own because the thread was a controversial one from the beginning).
If not, then the post probably never existed in the first place, or there was a glitch in the web browser or something and it didn't submit properly, in which case you can also calm down
So either way.... chill.
