The only place on here that I’ve noticed downvotes is on comments that have been obviously social media shills (reddit or meta) or right wing type comments that are not the type of thing a community should support in my opinion. I’m not saying you’re doing either of those things and if you’re being downvoted in another context I don’t know why.
That said, downvotes shouldn’t really get you down. If you’ve said something awful then you deserve them and should reassess your outlook if you were unaware that your views or attitude were unpleasant. If you’re getting downvoted on a tech related thing then I don’t know what that’s all about but I would try not to worry about it too much because it doesn’t really affect your life, it’s just a fake internet down arrow.
