I have nearly 50,000 posts on my Tumblr blog which I have been running since 2011. It is literally impossible for me to sift through all of that for every single “problematic” post just for fear of some jerk dredging up something I said eight years ago.
And honestly? I shouldn’t anyway. You can literally make the opposite argument: that it’s wrong to hide your past. If we all keep pretending that ideological purity is possible and erasing the journeys we’ve gone though to learn from mistakes and become better, more educated people I feel like that does more harm than good.
Anyway, your attitude is victim blaming. We should not normalize a culture of fear where everyone is desperate to hide their flaws because someone might start a harassment campaign against them. The solution is ending that culture, not saddling people with the burden of dealing with it.
