Dog socialization

I have a puppy who is 3 months old. My parents have a puppy that is 7 months old and is very DA and sometimes human aggressive. Every time I bring my puppy to their house (when invited), they try to force their dog on me and my puppy even though I have said no they cannot ever meet every time they ask about it. This situation has become frustrating to the point where I feel like I can't bring my puppy (I bring him so he can run/swim off leash). I know they are only doing it because they know me. They couldn't/wouldn't do this to a stranger or someone they didn't know well. I've tried explaining why I don't think it would be a good idea. Mainly I don't want my little 15lb puppy torn to shreds by their massive 50lb puppy who has already attacked my other older dog (Drew blood and caused a scar on her face when she was just 13 weeks old), bitten my boyfriend, and tried to attack a small child at a pet store. The dog had a history of abuse as a young puppy. I think that it needs to get some help from a dog behavior specialist and that until then I (and my dogs) will have nothing to do with her. Also I don't want my puppy picking up on her aggressive tendencies and having a negative experience with a dog at such a young age which will shape how he views dogs later on in life.



Am I being unreasonable for feeling this way? Or is there a better way of handling the situation? It's kind of complicated because family is involved and I just want what is best for my puppy.
