I've given up on chopping onions. I haven't chopped onions in at least 10 years and maybe 20. I use onion powder, dried minced onions, or frozen chopped onions in my cooking. That way I have no problems. I don't like massive quantities of onions in foods anyway. A little adds depth of flavor, but I don't care for food that tastes super oniony and I dislike raw onions, so these options work fine for me.
