wee b, i couldnt agree more if thats how people interpret things, the mere provision of a tactile sign doesnt achieve much other than to show what good guys people are cos theyve got a sign, so you are of course correct. there are much wider issues to consider for persons with all sorts of impairments
the point i was trying to make (very badly of course) is that if organisations such as rnib asked for them, then why shouldnt they be provided, its not for me as an able sighted person to tell them no cos i dont think its a good idea! there seems to be something immoral in making that assumption. i assume that because it is in the legislation that the arguments for and against have been considered and thats why they are recommended (or are they a requirement?)
what i am against is replacing them unnecessarily and i suppose this is where a risk assessment deems them unneccesary. i am also against quick fix companies pressuring people into buying or changing their signs because they can make a fast shilling
lastly, as i said before, if it makes us think of others and consider their difficulties then that is a bonus to the original intent.
