It's forums culture im afraid.
You will encounter WUM trolls, half wits, gobby internet hardman retards and the chavvy uneducated types.
Most of whom would never dare confront you in the boozer.
Just try to ignore it and chill out.
beware of one post who will preach to you that you must get down the walkers every week because its whats best for football.
you're just being silly now
