I did have this situation several times in the past. One thing that has worked well for me is to be a bit of a stubborn mofo in challenging people with arguments and not let go so easily.
I don't think you need to be arrogant, but you do need to know how to argue rationally. At least this works quite well with germanic-origin folks, maybe not so well in other contexts.
Another thing that helps is reputation, you do need to build that and that allows your arguments to be heard. No need really to be arrogant and loud IMO still.
This reputation thing, also brings other problems, because it's not good when people don't challenge you, then you need to find skeptics. This is very necessary when you do high end stuff.
