When Western (read typically white, middle class) feminist academics from american unis suggested a set of ways of targeting sexism and rape in India following the apparent surge of high-profile rape cases over there, Indian feminists sent back a sarcastic reply stating that they thanked the women for their suggestions, and obviously had no idea how to tackle problems in their own countries.
What business does a western women have attempting to pass judgement on issues in other religions/cultures if she is not a part of them, nor really knows much about them? That's a very colonial attitude, suggesting that we can go in and tell other countries or cultures how to solve their problems, especially when there are feminists in those countries already tackling these issues themselves. Feminism is not restricted to the west!
To illustrate this point, although not strictly about the particular issues you mentioned, this article shows why it's so dangerous of us to assume we know what's bad and have all the answers when it comes to other countries -
http://www.hup.harvard.edu/catalog.php?isbn=9780674725164There is a body of black feminist literature deriding western feminists of the second wave for their assumptions and basically racism, in believing that they spoke for all women everywhere, whereas in the third wave feminism as a movement is more conscious of not doing this, and of acknowledging the subjectivity and contradictions inherent in the movement and in women's lives.
There are groups, charities, organisations and initiatives in other countries working on all of the issues you've mentioned, you just don't here about them in our media.
Furthermore western feminists do indeed do things to help with these issues, again you just don't here about them and so assume they don't go on. Do a search for Womankind worldwide for example, a charity I support as a western feminist who apparently just spends all my time moaning about inconsequential issues...
It is also very problematic for you to state that some issues are 'real' or more deserving of feminist efforts than others, because they are ultimately all issues that effect women. If everyone thought that way, no one would ever have come up with a way soothe a sore throat or get rid of spots because we'd all be solely focused on finding cancer cures or tackling HIV which are obviously much bigger issues. We fight for the issues that matter to us and those around us, or those issues which we feel most strongly about and have the knowledge to fight for.
The word 'feminists' is so often used as an all-encompassing, catch-all category that can be used to say 'feminists do this', or 'feminists say this' when in fact feminism is an incredibly diverse, multicultural, multi-faceted and at times contradictory movement involving people with their own aims, problems, focuses, backgrounds, priorities etc. It is not a singularly-focused group of people that you can lump together as anti-feminists are so fond of doing.
I also think you are completely underestimating the power that 'rape encouraging songs' and the language we use with regards to women and relationships actually have on people's attitudes and so their behavior - this isn't trivial!
