States that are more welcoming of interracial couples?

You are looking at this incorrectly. States don't have attitudes, people do. There are towns, neighborhoods, and communities that are more and less conservative, more and less integrated, and more and less likely to have interracial couples. Rather than think of Texas as a single entity, look at population data fror specific cities. Houston is going be be different than Austin or Waco. Fort Worth is different from Dallas.

Austin is different from Brownsville just as San Francisco is different from San Bernardino. But the bottom line is that if you're looking for conflict you can usually find it (whether it's intended or not). So make your choices based on your needs and know that one or two idiots in a given place doesn't define that place.

I am from Wyoming and no one would discriminate you there. We would actually be shocked that more people are in town. Not kidding.

Most of the US isn't labeling people like that. The idiots that would be "offended" do not live in one place. I would pursue my life like none of those people exist, and enjoy the love you two have for each other.

Despite what the media tells you, most areas of the US are just fine with interracial couples and race relations. There are pockets in every state. If you're in a bigger city you will experience less of it.

Your sensitivity level appears high given that you are worried about such things to start with. I know many couples who wouldn't think twice about what other people say or how they act around them. The attitude you put out is often the attitude you get back.

This is based on personal experience having grown up in CA, being part of an interracial couple, and moving with my family to the East Coast / South.
