automatic liking - or not

I have a friend who clicks "like" on every comment I've ever made on his Facebook wall. This used to annoy me - surely he couldn't actually like every comment I make? - until I decided that was his way of assuring everyone that he'd read the comment.
So now I have to re-think that, because he wrote a Facebook post today that (though I'm sure he didn't realize it, or think of it this way) affirmed dominant male culture. So I wrote a comment that, essentially, suggested that there was another paradigm.
And guess what? My several-years-long streak of having every comment I've ever written on one of his posts get a "like" is now broken. He liked an innocuous, friendly comment I made on another post (and that was written slightly later today), so I know he saw it. He liked every other post on the affirmation-of-male-culture thread.
I'm wryly amused that something can break through his usual bland habit of "liking" every comment!
