I asked the question:
How would you like to see the viewing of pornography changed on public transport?
The options were:
1) A complete ban, similar to the ban on alcohol
2)A campaign for consideration of other passengers similar to the campaign to be considerate when listening to music
3) Not at all, I'm happy as it is
The results showed a clear gender divide - which does suggest it is an issue of sex-discrimination, in that it means that women and men feel differently in how offended they feel by porn when accessing public transport.
Unfortunately I had to end the poll early, because a silly chap decided to put a link up on his blog and the poll was suddenly flooded with other silly people who decided to sabotage the poll. Fortunately I had a guessed that it was about to happen after the silly blogger posted some silly comments. I took the results of the poll at the time before they could be corrupted. I deleted the said silly chap's comments and also others left by the poll saboteurs. I have kept some comments that make slightly interesting points though I disagree with the spirit in which they were left
