Cote I would say that the quran commands us to follow Muhammad, and the sahabah, that is why we follow hadith, I will find the verses.
And I would say that there is outcry in the Muslim communities about things such as fgm and preventing women from being educated, not having mosque facilities for women etc, if you go on any Muslim forum you are likely to see this, it is related to the trend of debating cultural based faith that many of the new age Muslims are doing, and they try to distance themselves and educate about these types of issues, starting with their own families. One of the major issues that Muslims oppossed to culture based faith spend a lot if time addressing is racism within Muslim communities.
And those niqaabis I mentioned that were politicaly active, this is the type of thing (fgmm, women prisoners etc) that they spend a lot of time campaigning, protesting and raising awareness about.
There are many organisations run by Muslim women, for Muslim women dealing with issues such as forced marriage or dv and they use Islam in their work to demonstrate how it is not condoned.
The issue if I wear it because I want to and it makes me feel good can also be seen as indicative of wider trends within society, in which the rights of the individual are paramount as long as it doesn't hurt anyone. Other examples could be open marriages, which we would say the same, as long as they are consenting, and it makes them feel good who are we to get involved.
This could be viewed as a result of secularisation, as the state does not dictate our moral bounds as much as previously, and we are free to choose from a spectrum of beliefs or spiritualaties, including those at either end.
