Intermarriage

I am studying the law of intermarriage, also known as the law not to marry a Non-Jew. According to the Torah, you are not supposed to marry a Non-Jew because of the assimilating in Egypt when Bnei Yisrael began to marry the Egyptians while they were in slavery. After researching this topic, it changed the way I thought about the mitzvah. At the beginning, I thought you weren't supposed to marry a Non-Jew because we were just taught not to and it just said it in the Torah not to. I never knew the real reason why were not to marry a Non-Jew. After finding out that it was because of the assimilating, I realized that many Jews are only marrying Non-Jews today because they don't have an understanding of why they shouldn't. So instead of finding out why they shouldn't they just assume it's ok and marry them. Now that i know more about the mitzvah, I have a reason to tell myself not to marry a Non-Jew.
