I am going to treat them much like I do when my difficult child is being disrespectful or looking for a fight. The ignore button works great. You won't even know that the person has posted and nobody has to be the wiser. As parents of children who do not grow up, use substances, can be violent and dangerous to us and who do the absurd, I personally prefer this be a sanctuary for me. This may not work for everybody, but from now on, that ignore button will go on faster. By getting pulled in, I add to the problem. So I'm practicing my new setting of boundaries on trolls too...lol.
