I've toyed with the idea, but haven't done it.
A few people have posted that they're ignoring me (a wise move), but I've yet to hit the button. In fact I'm not sure how to do it.
But... (and this is as close to a point as I get) is there not some Low-Cal insipidness to an online forum without the bits you dislike?
I watch large people buying Diet Coke and wonder whether they wouldn't be happier to have the full smack, but slightly less of it.
I like my forums full-sugar. Even if that sugar has a little jalapeno and maybe some sole-of-shoe unpleasantness in it. This is not a directed barb, just an indication of my distaste for some of the views I read. But I'd rather read them than not.
For the same reason, I occasionally buy and enjoy the Daily Telegraph and sit in a comfortable chair getting angry with the editorial.
Most people I know read only that part of the press which aligns with their political outlook. To me, that's the press version of 'ignore'.
