Wrong to invite girlfriend to Thanksgiving & Christmas?

Many people in my family bring their girlfriends/boyfriends to holidays. Also, most of my family is highly religious, but a few of my cousins are atheists. We all have a good time anyway, so I don't see a problem here. You might have to deal with some familial gossip, though.

 

You might have to deal with a few comments and questions but otherwise I wouldn't see much of an issue. Hope all goes well!

 

Well depending on how long you have been together, I think bringing her is a good idea and a first step towards self-security. Maybe don't bring her to everything, but include her. And don't worry about the atheist, as long as she doesn't present it too much, it will be fine

 

I think that it is an important step toward your family accepting the relationship
just be ready for the "homophobes" to either completely ignore you or give you hell

 

Damn. Maybe you should invite me!

I believe you've answered your own question, with:

Sounds like a simple but sensible plan.

As for the dealing with 'holiday views', this is also fairly simple.

Don't bring it up.

If they mention it, give simple answers. Hell, unless you want to tear the walls of ignorance down, I'd say amuse and appease them. Unless you're wanting to, use these holiday gatherings, as a platform for your own identity and life, again, just don't bring anything up. If forced into discussing such topics, keep it simple, keep it boring... and they'll stop, eventually.
