Bible says dating different races

So many people have said to mix race is sin and state it's in the Bible. Ok, When I have read this it's my understanding they were trying to "climb" their way into Heaven without actually believing spiritually. I am still unsure as to whether it is truly right or wrong. The passage has been interperated by many theologians though and you can easily research those.I have read the Bible many times and have failed to see anything pertaining to this. So, when GOD seen this the tower was toppled and HE created chaos by the different languages.....one couldn't understand the other.

And this one comes from a young Asian-American woman: “Dear Pastor John, my boyfriend and I are both believers in Christ and have been dating for almost 18 months.

My boyfriend really is trying to look at God’s word to see what God teaches on the issue of interracial marriage, he’s listened to many good sermons on the topic, but he still feels ‘in his conscience’ like it may be wrong to marry someone from another ethnic background.

I do believe that he created different races for a reason and he meant for us to not mix. If it wasn't for inventions of transportation then we wouldn't have been able to have access to each other as easily as we do now. I asked for Biblical proof and that's all that matters.

Since the Babel story comes after the Noah story we can assume there were already boats. I come to this conclusion because, why would there be separate races in the first place?

Here is a summary talking about the Tower of babble. I had never heard of it until I read this thread in here. I have nothing to back this up other than what I think.
