As an Arab woman living in Germany, can I fully integrate?

Yes if you don't practice Islam in Germany you will be welcomed

I was with the RAF in Germany After WW2 and i had many German Girlfriends and met their Parents

Most Germans were Very Nice My Favorite city is Berlin followed by Nuremburg

If you oppose Sharia, then it's okay.

I'm living in Germany for over 40y now - I've never seen any "real" Germans so far. Only assholes and non assholes, like anywhere else on the planet. 

Go and find real friends ;o) 

ures NEVER fully integrate in Deutschland unless you are German, sad fact? Of course

You can try too all luck goes with you.

You need to walk away from the murder/rape/torture/slavery cult of islam to do it, but yes, you can assimilate into German culture. 

Your American English is so STUNNING, I suggest you come to USA make America GREATER, hang out at a sleezy bar, meet and marry a beer dranker, and buy a house, with 40 year mortgage in the suburbs, ($400,000 and up), pay taxes only a rich man can afford, and after a few college courses (fits well with the beer appetite), get a job as a German professor or translator. get fatter and fatter, as most Americans, especially beer drankers, and enjoy retirement in 40 years! (and never leave the country, only WORK).

Sounds like you've integrated fine.

If you're asking whether people will ever stop seeing your Arab heritage - no. 

Can anyone "fully integrate"? Probably not, but you for sure can integrate.
