The difference is, the most visible proponents of Polygamy, USE polygamy as their excuse to commit these crimes against young women and children.<quoted text>
There are perfectly good laws against all the crimes your ignorance conjures up regarding polygamy. Use them. The crime you keep fantasizing about is not polygamy, it is child abuse.
If some people in same sex marriages commit crimes do you advocate banning same sex marriage too?
I am not saying it is correct that all polygamy should be associated because of this issue, it is not correct.
I am saying this is an image obstacle that needs to be overcome before progress can be made on this subject, as it will be near impossible to gain public support until there are more responsible people in the forefront of the issue, the imminent overturn of Prop 8 will have no effect on that part of the issue.
You do realize that same sex marriage would not have gained the progress it has without widespread public support, right or wrong... that is indeed the case, it needed, and had the support.
