How can I get my dog to go out with me??

Sounds like the dogs have no trust in you.
More info on the dogs and their environment and daily routine etc would be needed to give you any positive advice.

by giving them no choice in the matter

Just do it, collar/leash and go. Train the dogs, that's your responsibility, not the dogs and/or seek professional help for yourself on how to train dogs properly, before someone gets injured, dogs are removed at your expense, you're sued and they're euthanized.

Patience will pay off. Encourage him with treats, first place them near to him while sitting quietly in front of him keeping your voice low and your eyes down. Once he can come to you give him rubs and keep talking to him. If he growls get a muzzle and load it with his favourite treats, again be patient until he associates it with a reward. Once he accepts the muzzle and a collar and lead and encourage him to walk around the house on lead or with the lead dropped. then walk with him around the yard or garden getting near to the gate once he is happy open the gate and eventually outside. It may be that once you have him walking with you that a dog training class where he can be introduced, with muzzle on initially, to other dogs and owners.
He may have had some bad experiences and is therefore showing fear aggression, this can with time and lots of praise and reward come to trust you and be confident.

Train him with love he will understand you.
