Being a libertarian feminist who dislikes the unnecessarily hostile attacks on feminists by people alleging selves to be libertarians, I am even more sensitive to this issue. (I did an Amazon.com search of both her books and she does NOT call herself one in either.) 
 :::::I don't have a problem with saying that WP:RS identify her as a libertarian, even if they are wrong. I do have a problem with saying that so and so says she calls herself a libertarian without that person providing a reference to that fact.  
 :::::Also again please note there are some critical refs of Hoff Sommers - probably dicussed above  that are borderline WP:RS and a fourth opinion on those appreciated. (Or someone could bring them to Wikipedia:Reliable_sources/Noticeboard for further discussion; I can't decide myself so leaving them up.) 
 :::::Plus if third parties want to opine on if there is too much on the controversies. Of course controversies are part of what make people notable enough for wikipedia. -) Carol Moore ''''''
