There's no such thing as "choice" in Islam

In this post-modern, relativistic world that we live in, it's common to hear the assertion that "all religions are equally valid," or "no religion should be judged good or bad." This logic is utterly fallacious. When religions claim mutually exclusive truths, they can't both be right. One cannot accept the equal validity assertion and affirm basic truths upon which are nation is founded without obvious inconsistency.

Take women's' issues. With regards to human worth and dignity, I believe men and women and equal. There are obvious differences in emotional and physical characteristics which enable and equip each sex to better perform specific areas of societal contribution, yet at the most basic level of importance and value, male and female are equal.

The left especially has taken on the cause of "women's' rights" in the form of workplace opportunities, sexual freedom, and sexual irresponsibility (the first being generally positive, the last two negative). The left obviously champions and supports the right of women to work, dress, marry, sleep, and abort with absolute freedom. The "all religions are equally valid" also typically comes from left field. Yet Islam actively and purposefully oppresses women. Islam regards women as second-class citizens. They can't vote, they can't divorce, they can't...the list goes on. In Islam an arranged marriage is standard fare, a strict dress-code is enforced, and a victim of rape--yes, rape--may be punished by death.

Are the "rights" of women in Islam somehow equivalent to those in the West, in America? How can the left champion both the "unalienable rights" of women and simultaneously support Islam as morally equal to the West?
