It's not meaningless nor is it toxic. Forcing everyone to write posts to each and every post you see on forum that you don't agree with is toxic. Like do we really have to spend time answering bullshit posts every day on balance forums or somewhere else so that we are heard that in fact we do dissaggree with the take of OP?
Like how is the "I don't agree with this post" button toxic to you people? It's literally the same shit but more efficient than having to write stupid response to each and every post. I mean, I can go back to responding to each and every asinine post people write but I'm sure magge and few others will have a few words with me soon enough.
Also, it's mostly stupid out of touch posts that get downvoted. If you will look at the reasonable ones they will often just get stupid amount of upvotes without any downvote.
