As a general rule, I pretty much leave posts up and allow a wide variety of subjects and posters on the forum. I like to use the great McLaren Fields tactics on "trolls" the tried and tested point and laugh strategy.
People will invariably have differing views and the very tribal nature of sport and RL in particular will always bring these to the surface and will grate on some.
That being said, if people feel like there is a troll on the forum please let either myself or Frosties know and we will look into this in confidence, our DM's are available for you to use.
Aside from that, I am in complete agreement with the tone of social media these days, everything is so confrontational and absolute black or white, for or against when in reality, there is a definitive "grey area" on most subjects.
