it is a very difficult decision on what to tweet about,not to upset anyone on twitter at all.
but i do think on balance important issues should be tweeted about to raise awareness and cause discussion.
because twitter is full of people from different religions and people unfortunately suffering from a vast range of illness/disorders and then you need to consider things like race and gender.
opponions are so widely and greatly different and interprations vary vastly it becomes almost impossible not to occassionally effect someone.
i do think it is important to try and be tastefull and tread carefully but peoples variation on issues is fantastic-so well done twitter for allowing us to get to know so many brilliant and varied people
