Is feminism still relevant in contemporary western societies? Why?
By and large, I don't think feminism has the same relevance that it did years ago because women have made so many gains because of it, and plenty of laws give women favourable treatment. There is still some relevance, though, since double standards that favour men still exist.
What are some pros and cons of feminism?
I think that feminism helps encourage women's education and success, but at the same time, radical feminism often paints a negative image of men and some feminists take offence to men being courteous towards women. They might also interpret things as sexist even if they aren't. One of my main criticisms of Western feminism is the bulk of it consisting of white, middle class, liberal women. Minority women and conservative women can be feminists too. Plus feminists can have very differing opinions on certain manners. There are pro-pornography feminists, despite most of the movement being anti-pornography. There are also feminists who incorporate religious teachings in their feminist beliefs, while other feminists view all religion as sexist. Feminism is not monolithic.
Are you a feminist? Do you personally agree with feminism? Why?
Somewhat, but my feminist beliefs tend to focus more on Muslim women. After all, I think feminism could really benefit Muslim women. At one point, Muslim women had a lot of freedom compared to Western women, but Western women's rights have progressed very significantly compared to the ones that Muslim women have. And being a Muslim myself, I'm sick of seeing Muslim men abusing their wives and daughters (or worse, killing them). This cruel treatment has no basis in Islam.
For example, I strongly discourage polygamy, which I see as archaic. I also think that Muslim women shouldn't be required to cover their heads (though they can cover their heads if they want to). Muslim women should also have equality in divorce and inheritance, and domestic violence and honour killings should be outlawed. Muslim girls also deserve the right to education.
Despite this, I think feminism should benefit all women. I personally agree that feminism is a good idea. However, I am opposed to the radical feminism preached by women such as Andrea Dworkin. Women treating men as inferiors is no better than men treating women as inferiors.
Are there sexist overtones in feminism?
Depends. In equality-based feminism, there are usually no sexist overtones and men are accepted in the movement. Though feminism is obviously dominated by women, men have played a significant role in feminism as well. In radical feminism (or "feminazism"), on the other hand, I think that there is a lot of misandry that encourages women to act rude towards men. These women treat all men as criminals, rapists, and misogynists. Men and women should be equal - one gender should not be superior to the other.
Besides, not all feminists in history were social justice people either. Take a look at good ol' Rebecca Latimer Felton, who is nowadays more known for her extreme racism than her feminism:
