I do think you have made a good effort. On the other hand perhaps in the interest of reaching more people and lessing the risk of people "shutting down" at the sight of the signs minor changes could be made.
I don't think necessarily that everyone who has been a victim of some sort of physical or sexual abuse or molestation automatically equates the WT with such abuse or fully comprehends at present how their policies may have prevented them from getting the help they needed.
Also most Witnesses will automatically assume you are attacking their stand on blood or implying "spiritual abuse" and miss the point. From their perspective, only opposers make up these "false" claims that abuse even exists.
What you want more than to put the WT in a bad light is for people who have been victims get the help they need.
You might want to approach it from the point of view that "Some who were victims of sexual abuse were mistakenly advised not to get the help they needed to avoid bringing reproach on the organization. The Society now encourages these ones to come forward and seek help if they need or desire such help. Please contact (phone number) or visit www.silentlambs.com for assistance.
I know that is alot more complex than your signs but something along those lines might reach more victims and appear less "apostate". Your phone number, 1-800-WT Abuse might be better listed as all numerics.
Again, these are just alternative suggestions and I'm not suggesting that your signs are incorrect in any way. Just that the primary thing is that you want to see that victims get help, but don't "shut down" out of a fear of "apostate propaganda".
