It's an interesting question. I think it's a bit of balancing act. But of course there is indeed a difference between challenging the poster's opinion and attacking the poster themselves.
Until recently I was using another parenting forum. I liked posing topics I thought would raise discussion and be of interest. I enjoyed it and have a pretty thick skin so am not afraid to hold my own in a debate and post some more controversial topics. I like getting stuck into more 'meaty' topics I suppose as well as more light hearted chatting.
But I'm afraid over the couple of years I was there, there were times I was bullied or harassed by two or 3 other posters. They would immediately disagree with anything I said, made so many personal remarks about me, took sides with their chums, stalked me around the forum. Not nice. Many others noticed it was harassment and tried to stop it but alas the admin did not.
Is it bullying? I don't know. Maybe. It's certainly harassment.
It's not as easy as just switching off the screen either. I had friends on that site I didn't want to leave and who were urging me to carry on regardless. I have a strong sense of justice. I didn't see why I should be intimidated by a few friends who clubbed together like girls in a playground and were utter hypocrites.
So at the moment I am aware of all this as an issue. But, although I will miss my friends, I am glad I've found mums net. Loads more posters and threads here!
Ooh, that was cathartic. Thanks for starting this thread Seeker. As you were, rant over!!
