Although, I am not criticising the marriage of Aisha (ra) - in that he was a prophet and we can't compare, I don't think, as trumble argued, the arguements are really good to use.

Should stick to prophetic arguements imho (as some notable scholars do, rightfully).

I know you said no debate, but really, some of this is really bad dawah. Stuff like culturual norms is not a valid arguement, nor is it the reason the Prophet (saw) did it. A lot of things were cultural norms and were not allowed. Just because somthing he did was, doesn't mean he did it because it was cultural norm.

I only post this in that, people should be more careful as to what people teach others to use as dawah - as it can backfire pretty badly.
