Sounds silly, but instead of a muzzle, you might try a bandana...for some reason, people think dogs just look friendlier when they're wearing one....or perhaps an "in-training" vest...you don't need to say what he's in training for...just having that on him might put people at ease a little. I think now is definitely the time that you need to get him out there and show off what a well-behaved dog he is to people that might be generalizing that all Rottweilers are evil creatures. Show them that you have complete control of him and he is a good addition to the community!!!
