In also only just downvoted an didn’t leave a comment. Only after reading your answer I wrote this. The problem is (and it’s probably very hard to overcome), is that people often look for validation and getting downvoted doesn’t feels good because it’s the exact opposite of validation.

But keep in mind that nobody (ok at least me 🤣) downvotes you because I want to hurt your feelings or “to silence” you. Don’t get me wrong but I couldn’t care less. I don’t know you, I don’t know your past, what you do, your mindset, your attitude. All I see is a post I don’t agree with and by downvoting I’m just contributing to a statistic that let’s you and other users know how others roughly think about that post.

I think we should try not to take downvotes to serious. Unless all your posts are downvoted all the time (which could indicate all sort of things) getting some posts downvoted sometimes is perfectly healthy and normal, so try not to take it too personal because non of those people know you, all the know is what you wrote and it didn’t resonate with them.
