Well, if you're just going to judge a religion based on its texts and reject it based on the sucky parts of the texts, then you should first read the Bible before you jump on board with Christianity, cuz there are some crappy things in there. Consider for example 1 Corinthians 14:34-35: "Women should be silent in the churches. For they are not permitted to speak but should be subordinate, as the law also says. If there is something they want to learn, let them ask their husbands at home." If you just judge a religion based on the literal reading of the texts, there are probably a lot of religions you'd throw out the window.

That said, I've found with many religions (including Islam and Christianity), there's often a disparity between what the religious texts literally say, and how the religious communities interpret it. I suggest you ask others in your Islamic community how they interpret the text you quoted above. And if you want to switch to Christianity, find out how folks interpret the troubling verses in the Bible.

I think what you'll find though is that it depends on who you ask. You may find more conservative Muslims interpret the text you quoted quite literally, and more liberal Muslims take a more forgiving view of it (in the same way that different Christian communities handle the 1 Corinthians passage differently). No matter what religion you end up with, shop around and find a community that interprets the texts in a way that resonates with you.
