Like others I'm not a fan of ignoring people, but you do make a good point. We're all equal here, we all put our names to what we say and we all have the right to voice our opinions. I knew my post was hypocritical even as I typed it, but I still couldn't yield to the voice inside my head saying "Don't bother posting!". Overall it would probably be better if I could.
I think it's easy to want to answer posts that you feel are dragging things down; if the overly (in my opinion!) negative posters are posting more often it makes the whole rF2 picture look bad, so it's tempting to counter that in the hope of encouraging any new visitors to stick around. And I say that as someone with fairly reasonable (obviously in my opinion) objections to some aspects of rF2 development - I just don't extend that to all aspects of rF2 as a whole.
But, need to remember any visitors can make up their own minds. If someone is making a twit of themselves a visitor can work that out. It doesn't really need anyone else to post about it. And I think any regular forum user should have learnt that arguing with people on a forum rarely succeeds in changing opinions
