A problem is that one has limited time and energy to respond to these comments, though the idea you've mentioned has motivated responses I've made in the past. It can be draining to submit a well-sourced comment written respectfully, then get downvoted (this is more prevalent on Reddit) where fewer people see it.
I've resolved to avoid responses, unless it's a subject where I have an especially valuable perspective (e.g. personal expertise, I have a passage from a credible book that could be relevant, or I have a highly relevant anecdote to share).
It's almost always not worth it to get involved in a controversial topic discussion (examples include journalism, Apple products, urban planning and whether the ending of a popular television series was good or not). It can be distracting and draining, especially if people respond negatively or you get downvoted (I tell myself it's just internet points, but it feels punishing despite my rational thoughts), and I'm unlikely to change minds. There's more to life that's more rewarding (e.g. reading a book, physical exercise, even playing a relaxing video game for a few minutes).
