You value open discussions of difficult ideas, but want to stop irritating strangers and stressing yourself out. You have nailed a core dilemma of online comments. Just know that everyone's vulnerable when exposing their private ideas online. Create psychological safety by showing that you hear them and demonstrating that you're willing to focus on common ground. Force yourself to write something good about the post you're replying to first, or try to restate their argument in the strongest possible way up front. Be clear about your differences, but note what evidence or experiences might change your mind. Close by emphasizing points of agreement. This approach doesn't guarantee civility, but ups the odds. If your goal is really just creating space for you to cool off and walk away, this exercise can help for that too. Iron-manning someone's ideas can help make them seem less urgent. If that's not fast enough and you really just want to turn your reactions to comments off, mindfulness might work. You would want to focus not just on your breath, but specifically on observing your triggers and how you process them emotionally.
