Yes, when shortly after someone makes a post you make a post in which you blatantly insult the poster and do this every time that person posts, that is stalking. Everyone knows very well who you are insulting and just because you are too much of a coward to address your posts to the person you are viciously attacking, does not mean that you are not a stalker.
But of course, we know why you do it. You know that your side cannot refute the arguments being made against your atheistic theory you so deeply love so you try to disrupt the thread and perhaps have it pulled by turning it into a slime-a-thon.
