There are some forumites whose posts I will never read because I don't like how they post. I will skip anyone who is regularly cruel, rude, aggressive, childish, makes personal attacks etc. I'm probably not alone in that. Conversely, there are some forumites whose threads I follow even though I don't agree with a word they write, but I find their arguments compelling. If you are going to be cruel or make personal attacks then you do need to accept that that there are forumites you will alienate in the process. Personally, I come on the forum for some light relief, not to be wound up, so I just automatically censor certain forumites by not reading their posts (or the pointless threads they start). I don't mind a good argument - let's face it they can be really amusing. For me, cruelty and rudeness cross a line - there's just no need.
