I got attacked by someone for discussing a rape experience on a rape support subreddit very early on in my reddit days so I stopped clicking the envelope altogether. I didn't stop sharing my views and personal experiences in subreddits because I know there are people in the world who could use the knowledge that others have been through the same thing (my aforementioned post was basically a detailed "me too" in response to someone else) but I just had too much anxiety to see whether another jerk had come out of the woodworks. By just reading the subreddits themselves I knew there were moderators and down votes to handle the worst offenders and well, the attacks weren't likely to be personal since the front page has a high turnover rate and I was unlikely to come back across a comment I made.
