As has been said on many platforms...
DON'T FEED THE TROLLS
Use the Ignore function. Unfortunately, others sometimes quote someone you have on your Ignore list as they (hopelessly) try to make their own point, or defend their own beliefs. I wish the Ignore was more like a Block function, so it would be impossible for you to see any of their posts, any quotes of their posts, and they would also be unable to see anything you post.
