For me, all it took was learning to just let myself decide to do nothing when I think someone is wrong, even if I feel that view or speech or whatever might be harmful to them or others in some moralistic sense, and especially if I find myself already frustrated before I've engaged. Everything isn't up to everyone to sort out all the time, and it's been hugely freeing to just let it go and focus on literally anything else in my life. The internet has a way of making us over-value the thoughts and opinions of strangers sometimes (seemingly particularly those we have nothing in common with and nothing to gain from arguing with).
