"It seems when I 'challenge' a poster's opinion (lately) it gets labelled as being 'aggressive'."
Pan, the responses to you were to this post:
"Lordy. Have you heard yourselves? Non-issue aggression? Personal undermining.? Wild deliberate misinterpretation. It reads like a feeding frenzy on another woman as if she had poo-ed on your best-drawn picture at primary school. One or two of you really need to grow up."
That's not actually challenging anyone's opinion, is it, it's telling women how to debate.
If you can't see why that is offensive, then yeah, this probably has stopped being the right space for you. Regular posters here tend to react not very well to men telling us how we should talk to each other.
