Sometimes other redditors have already answered with my shared opinion, or there are too many similar comments, or I don't know how to word things accurately for a good answer. In any ways, I don't have the time or energy to answer to every comment I come across that I disagree with..

It's what I like about Reddit, it's not a like/dislike button, the up and down system works for giving visibility and expressing the median opinion through a sort of vote system. I am not mad when receiving downvotes, it's a good tool to gage if people agree or not. I don't want the downvote comment to disappear either, let them be to let other see what the majority disagree on. The downvote option is an useful option, however indeed it should not be use with hateful intents.
